It's on the SS board (third or second one down).

It should have TRACKING on it next to the pot.

HI

I am new here.

I get 2 x Sony SL C9 - one in bad condition for spares another I hope will be able to fix.

Problem is that I can not find service manual - can somebody have it? willing to send it?

Failure is that it wont load the tape ... rechecked all micro switches for casset accept, for both positions , tape in - all seems OK...

any idea what else can be problem?

Thanks

Hi everyone - my first post!

I was recently given a Sony SL-30 (1984?). It's in fair condition, but a has weird issue..

When plugged in, the spool motor spins up for about five seconds, shuts off and the tape mech. goes through a routine of loading / ejecting 3 times (no tape inside), finishing in the loaded state.

All front-panel controls are unresponsive at this point, including the power button (remains on) - the clock however, can be set ok.

I can get a tape into the machine during it's crazy load/eject cycle if I'm very quick! - once in, the machine appears to operate normally.

Have removed the black leaf switch to the RH side of the loading mech and cleaned the contacts. It's not that it would seem.

Many thanks for any tips :)

Thanks Kevin - good to hear from you.

The machine had pretty low hours on it from what I can tell, so hoping its just aging electronics that need a tweak. Tape path and mechanical alignments look untouched (original paint intact), no sync problems on playback - and applying a slight force to the ACE head (left/right/down) doesn't change the volume at all, so I'm assuming alignment is okay.

I assume it's the "AM5 board" I need to look at? It's either at the rear or perhaps underneath the tuner - I can find that out.

When I use "your" VTC5000, the VU meters on my transfer equipment peak around -12db. The problem HF100 peaks at around -18db. It's not terrible, but could be improved.

If you think the pot is labelled with something obvious I'll take another look.

Rob.

Hi Rob

That issue on the SLHF100 is common.

The Sanyo M40 seems to have a better overall mono edge track sound than the Sony HF100.

It could either be high usage and the control track mono sound head is a bit worn or dirty (not that likely).

It could be you have a bad component to the mono sound board and you can increase the output and recording level.

They are labelled and under a silver can to the top or second board as I remember.

IF the pot's don't allow adjustment then the IC or a cap or two has probably failed.

I have worked on a Sanyo M20 and two M40 's where that mono sound IC had indeed failed as you couldn't increase the output, and recording was low there too. On the later Beta's the IC did more work than on the earlier ones ,so if it went wrong then other parameters were not able to compensate.

Obviously look at head wear ,tape path alignment and dirt first. Also back tension too.

Hope this helps........................Kevin

Hi all,

I have 3 Sony HF100s. All work okay, but I find one of them plays a little quiet (normal audio), although beta Hi-fi appears fine. I have never been able to find a HF100 service/adjustment manual but understood many of the electrical adjustments are the same as a C30 - is that correct?

I don't have an alignment tape (but do have a scope). Could anyone advise on a simple method for increasing the (normal) audio output level on my machine?. I never have any sync issues, so assume the ACE head is pretty much mechanically aligned.

Any advice gratefully received.

Hi manuel,

I think your machine has a worn or dirty Audio/Control head.

It is part of the ACE Head Assy.

There is more about it in the Repair Centre.

It looks like an ordinary Tape Head.

It records and plays back the Mono audio, Top track.

The bottom track controls the tape movement.

When worn, or needs cleaning.

You get the results in play back, and recording.

That you are telling us about.

It is most probably Worn.

And will need replacing.

But it is now.

Very difficult to find new ACE Head Assys.

Hope this helps.

Hi steve,

check that the video input selector switch is being operated correctly.

It maybe that if this machine has had it's front panel removed.

That the correct posn of the PCB mounted switch wasn't correctly alaigned.

When it was replaced.

Therefore not set to the correct posn.

When you select Video input.

I have the video BNC connector and my dvd player is attached to both audio/video in but still not getting signals into the Sony SL-HF950. I am thinking that the input circuitry maybe at fault. I can play prerecorded tapes okay but can't record any video or audio input signals.

For steve tutty,

The scart socket on the SLHF 950 is for playback only.

However you can modify this.

By wiring to the audio and video inputs.

You can get the scart pinout from the internet.

I have used what I called Phono cable, which is screened.

I got mine from Maplin Electronics, in the UK.

Not sure if they are still on the go.

Also it would be good to know.

Of the setup that you would be using this video in.

Say From a TV or Set Top Box.

And What types of AV connectors are provided.

You can get a Phono to BNC adaptor of Ebay.

This will allow you to connect to the Video in.

From A Phono Lead.

Usually Black 3 way, Red White and Yellow connectors.

Yellow is for the Video signal.

You can get a Scart plug which is switchable.

It has the three Red White and Yellow Phono Sockets.

That you can plug up the Black 3 way cable.

Making up a Scart To The Phono, Audio Inputs, and BNC Video Input.

Hope this helps you.

Steven,

Failure of the SLHF950 power supply is quite common after all these years. The design is basically a 240VAC to 12V DC (@4Amp) switch mode supply followed by a DC to DC switch mode which generates all the required voltages needed by the VCR.

The capacitors age and dry out losing capacity plus their ESR increases and the result is the failure of the first AC to DC convertor power transistors and other components.

Indeed capacitor aging effects other aspects of the VCRs operation as well but most can be rectified by adjustment or replacement.

Whilst these issues can sometimes be repaired my solution is to replace the first section with a modern and more efficient switch mode power supply connected the the second DC/DC section in the SLHF950.

See https://www.ebay.com.au/itm/AU-Power-Supply-Adapter-Transformer-AC240V-To-DC12V-2-3-5-6-8-10A-for-LED-Strip/162567927732?hash=item25d9cdb7b4:m:mJucG2iLZGn9TWRzhqLSWZA (they seem to be commonly used for LED strips)

You could use this external to the machine but if you mount it in the machine an earth wire must be added because the machine can float at half mains voltage due the the leakage generated by the mains EMC filters.

Update on the problem tape: I cleaned it - no more head clogs - I passed a microfiber cloth over the tape both sides using rewind and fast forward functions - I held the cloth bound to a slender rod held vertically - no apparent damage to the magnetic recording though it is starting to deteriorate with age (some blackframes) (28 years old +) - recorded in superbeta I now transferred contents (boxing matches) to digital - image is still sharp. I'm amazed how resilient the Betacord machine is (not the one I used to record - I lost that one) . Thanks to all the cleaning tips (external and dis-assembly , on this site.

@ William - Try hairbands from the dollar store for band pulleys if you have these kind of stores where you are - they come in all different sizes, have the right kind of stretch and will last, Worked for me for the small one for the cassette driver. Pure elastic bands also work but might have a more limited shelf life. . They sell packages of elastic bands of assorted sizes and thicknesses.

The hairband has a wrapping around the elastic which makes it more durable.

Hi all,

For your interest ---

I have recently converted tapes to digital from a Betacord Sanyo model 3900. One particular tape is a challenge. It caused the cassette driver to slow down and the cassette driver band broke. (The tape mangled and I ended up splicing it and repairing the splice.

I replaced the broken band , first with elastic bands which had a shelf life of about 6 hours .. then with a small hairband from the dollar store (Almost perfect size , I brushed plastic cement on it to give it some more tightness and friction . Works perfectly.

Back to the tape - I got it going - wind and rewind at speed not and played a few times but I can't get a clean digital transfer - often, problem is at certain sections - it keeps clogging the heads for some sections of the three hour recording. Testing shows the data is still there over these sections but it is as if the sections are randomly dirty I have to use tape cleaner cassette or play another clean tape to get the heads back reading. Time consuming and dangerous for the heads.

...

So, whats with this tape ? Is it dirty or does the clogging come from the tape itself degrading in some way and bits of it coming off?? I've attempted some kind of clean - running the tape at rewind brushing it over a microfibre cloth held vertically wrapped around a Q-tip - so far with uncertain results. I'm puzzled what the problem is which is my question. I'd like to experiment more but I'm taking a chance on messing up the cassette driving mechanism which I almost did several times.

Thanks.

Max

Siftyzod:

That issue is very common on the VTC 5000 and 5150.It's also starting to occasionally show on the 'M' series models too.

There are two upgrades you can make.

One has been known to stop the reverse play mode functioning. It seems the earlier the machine the more likely this is to happen.

The R49 fusible resistor on the syscon board (the one to the extreme left of the vcr.

It's located inside the metal heat sync near the top centre. With two heat sleeves on both of it's leg's.

The other safer one is change R3054 (R54) to 120ohm, also located on the same board.

It also benefit's to re groove the ribbed spool edges on both spools with a suitable needle (nothing bigger than this) as on many I've seen of the 5000/5150 these are nearly flat through high usage. It will help with the FF/REW and unlacing speeds torques slightly too. It's not always the idler tyre (as many seem to think) if the tyre is hard and cracked then yes, but... if it's still pliable with no split's or cracks, lightly rough the outer edge with 120 grit to give it back the newer surface that grips better. Lightly is the word though. A new reel belt is usually required too if still original. Also a tiny drop of oil to the top of the reel motor shaft (where it enters the motor as this can be quite dry too and you will notice the motors peps up when doing this.

Only a tiny drop to the tip of a miniature screwdriver though and just to that area! (please keep WD40 well away from these mechanisms.I've seen two covered in the stuff all over friction bands and everywhere it should not be. You have been warned.

Hope this helps......................Kevin

Hi there.

I have a sanyo 5150 i have replaced the idler wheel and belts but the tape is still not lacing back into the cassette and it randomly stops playing and doesnt unlace .

its starting to destroy a lot of old tapes and wondering if anyone has had this issue before.

if its going to be to much of a job to repair i will just dump it.

any help would be good on this issue as i am out of ideas

Hi Rezinagro

I have a friend who has both the C30 and the T20. The machines are identical. The T20 was sold in the Middle East and Saudi Arabia while the C30 was sold in the UK, Europe and Australia. The main difference is in the SECAM circuit.

Hi Everyone,

I've just joined the forum and would like to say Hi.

I have some information for those of you own Plasma TV's which you use with a Betamax VCR. Many Betamax models work fine of course with Plasma TV's but in previous messages here I notice a couple of people including myself have experienced issues with the picture on Playback.

Sanyo M20 and NX100 seem fine but when using my Sanyo 5000 I noticed speckles or white dots like interference on the screen.

This seems to happen when you connect to your TV via a Hard Drive or HD/DVD Recorder which then goes through HDMI into your TV.

The interference does not seem to happen when you connect direct to TV via Scart, AV3(Phono/RCA Leads) or RF.

I even used the same machine that caused the issues through HDMI and issues this time didn't happen when connecting Betamax VCR via AV3 input - Not Scart adaptor.

Hope this may be of help to some of you.

Hi there,

Maybe someone can help me with an issue on my Sony SL-F30. Playback is good, but it will shift to black and white image every time

a drop on the tape is found (sometimes it will play BW straight away after ingesting the tape).

I can eventually revert to colour playback turning the tracking button to an extreme position (up or down) but it

will soon get back to B/W again. I've tried to clean the heads with a paper and a bit of isopropyl alcohol, but it doesn't really get any better.

Any help will be highly appreciated. Thanks in advance.

Rob,

In that case the timer is not your main issue. The machine sounds like it needs a belt kit overhaul.

The solenoid brings in a gear to drive the un-spool and collect tape action and then eject the cassette (if one is loaded)

If there is no cassette in the machine then the tape lid should pop up unless something is jammed.

This model had a retro fit metal drive gear and stronger spring to ensure that the tape reels gathered the tape and also that rewind function did not fail as the reel drive rubbers aged and hardened.

I am not sure if this model machine uses metal slides similar to the SLC6 which is front loader but the C6s are now failing to operate due to grease hardening and stopping the slides moving.

So, I suggest you pull the machine apart and observe the solenoid action and see if the drive motor is working and check the condition of the belts and replace where necessary. You will need to remove the top and bottom covers and swing the base boards out to get to the mechanicals after removing the screws.

I have thrown out all of my old C5, C7 machines because they have too many issues and top load is not popular.

Hi Noel,

Unfortunately it wasn't the clock/timer switches this time. Replaced all of them but don't even get the channel number led on power on now.

I can set the clock and time though so a small victory.

On power on no buttons do anything except eject which clicks the solenoid but doesn't actually pop the cassette carriage.

Will have to dive properly into the service manual I guess.

Thanks Noel,

That's interesting. I got a bag of replacement tactile switches for this project but was going to do that last . I assumed I was missing something on that syscon board as replacing Q25 definitely cured something as the channel number led now lights up when you come out of stand by. It just didn't fix the lack of response to front buttons problem. .

Let me replacement those (19?) Switches on the clock board and see what happens.

( Still got to fix that 8800 you sent me some circuit diagrams for but that remains in the 'hard' pile for now )

The SLC7 timer board locks up the machines functions because the push buttons collapse and short out

The easy fix is to desolder and remove them

If you want to just be able to set the time to stop the display flashing then you need enough good switches left to set the clock

Hello,

Does anyone out there have an SL-F90. The info on here says it has on screen displays but i cant seem to make that work? The RMT-223 supplied isn't working and i'm using an old Sony VHS remote, (RMT-V474), which has them VCR 1, 2 and 3 modes... Maybe its just a remote issue? I have a spare RMT-223 somewhere so will try to find that. All in all a fantastic machine!

Anthony : Cela dépend de ton utilisation. Si tu veux lire de vieilles cassettes françaises tu dois prendre un SECAM comme le SL-C9 F. Si tu veux pouvoir lire des K7 PAL en plus il te faut un PAL / SECAM comme le SL-HF950ES. LE SL-T50ME lit le NTSC en plus. LE SL-T20 est une version basique qui ne lit pas le NTSC. Les SL-C9 F sont assez rares à ma connaissance (j'en ai un, avec un SL-T50ME et un SL-HF950ES ) et c'est un des 2 hauts de gamme avec le SL-HF950ES car ils ont des ralentis avant et arrière et compteurs en temps réel.

Hello everyone,

For my sins, I am trying to revive a Sony C7UB. (It was pretty much new/boxed so I had to take it on).

It's the Mark I (no labels on the front right flap) so assumed I needed to re-cap the power supply which I now done. I have also removed the battery, although it doesn't appear to have leaked. My question is around the "no function" tip on here.

After re-capping the power board, my voltage rails seem okay. On mains power (standby), the clock is fine. When taken out of standby, I got no channel number and no buttons functioned.

I replaced transistor Q25 on the SysCon board and that gave me back my channel number, but still the front buttons do nothing. There is no attempt to lace, although the led on the button responds.

The Palsite entry says "No functions - Check regulator transistor Q25 [2SC13641] zener diode D)gon the system control panel".

Q) What is the tip about the zener? I assume there is a typo as what does D)g mean? I assume a particular zener is needing replacement?

Anyone done this and know what zener I need to replace?

Thanks in advance

Rob

Thanks guys.

I will just have to do some investigating then. Both failed suddenly while I was working on them. One when I turned it upside down????

Hi Noel:

The only info I can find for a similar issue with the Sony 'C' series is...

No play with capstan going really fast. Change C325 and C323 both 4.7uf tantalum caps.

I still have not discovered my issue with the capstan speed being OK but the reel motor in play going too fast when warmed up and even with the torque pot at minimum it's still too high a torque at 100.

Hope the former sorts your issues out though.

Hi Noel,

Apparently nobody has. (Or everybody is on vacation without internet). If you mean the pickup reel doesn't rotate I can imagine what happens with

the tape if the capstan goes fast and the safety mechanism doesn't stop this. Which models are these 2 machines ? HF950, C9 ??

What would you suspect on a machine that has some video and synchro problems, sometimes a pink stripe fluttering on top of picture, sometimes black screen for a few seconds, or vertical instability... ? All heads are clean... Maybe the control head is worn ? Does this happen ? Or is it possible that due to aging the tape path is too low or too high in front of the control head ? What would you try to fix this problem ?

Regards, and I wish good holidays to everyone.

HI guys,

My turn to ask. Has anyone experienced and fixed a fault that causes the capstan to go really fast whilst the forward pickup reel does nothing at all?

Has just happened to two machines I am working on so thought I might ask.

cheers Noel

Lydia,

If you want to send your machine to Noel in Melbourne, I can recoomend SmartSend (www.smartsend.com.au)

I have found them reliable and very cost effective.

Had really bad experiences with Couriers Please, twice equipment arrived badly damaged.

Lydia,

Re fixing your SLHF950. I am in Melbourne. I can probably fix your machine. Transports screws not being inserted do not make the machine dead that sounds like a power supply issue. The lack of screws usually makes the plastic tray slides subject to damage. They can also be repaired.

My contact details are at http://www.palsite.com/directory.html

Malheureusement, faute de trouver une solution, j'ai vendu l'appareil hier.

Un type l'a pris pour avoir des pièces de côté.

Je passe à autre chose car je ne m'y connais pas et pas les moyens de faire une réparation.

J'ai repéré deux betamax près de chez moi. Je dois aller y jeter un coup d'œil. Ca semble être des machines qui fonctionnent.

PS : Je pense que tu as compris que Noel t'a dit de bien nettoyer le bloc CTRL (fixe qui contient la tête audio et surtout celle du signal de contrôle) car dans un cas extrême d'encrassement de cette tête le scope peut s'arrêter ne détectant plus le signal de contrôle. Il a aussi remarqué comme moi que la bande parait bien détendue sur le côté droit ce qui enclenche le mécanisme de protection qui arrête la bande immédiatement si c'est le cas. Il peut y avoir un problème de tension de bande, sur le SL-C9 il y a un réglage, mais il faut le maîtriser...

Anthony :

Effectivement après avoir vu ta vidéo je remarque que le tambour de têtes tourne donc ce n'est pas le hall effect sensor. Mais tu as bien fait de le gratter par le dessous, il faut que toute trace de marron disparaisse, moi je l'ai fait sur mes 3 beta ( SL-HF950 ES, SL-C9 F et SL-T50ME ) après avoir eu le problème sur le 950. J'ai tout gratté avec une aiguille puis nettoyé au coton tige imbibé d'alcool et attendu un bon moment que ça sèche avant de rebrancher. Je suspecte plutôt un détecteur de bande ou un C.I. / transistor claqué. Ou bien un problème de tension, ça me parait un peu détendu côté droit. Pendant les 2 secondes où il tourne tu as le temps de voir une image même très courte et un son ou pas ?? C'est un achat récent que tu as pris en l'état ou un appareil qui marchait et qui a développé la panne récemment ? C'est sans doute un truc de 3 fois rien facile à réparer mais le plus difficile c'est de trouver !

J'ai moi-même eu des problèmes avec mes 3 beta, normal, combien d'appareils récents fonctionneront encore dans plus de 35 ans ??!!

Kevin (UK) Gabriel (Espagne) et Noel (Australie) sont parmi ceux qui m'ont le plus aidé, je ne suis pas pro mais assez bricoleur sur ce type de machines, j'espère qu'ils voudront bien se pencher sur ton cas. Si tu l'envoyais à Kevin je pense qu'il te le réparerait sans problème mais ce ne sera pas gratuit naturellement, surtout avec le port aller et retour, il faut voir si le jeu en vaut la chandelle, si tu tiens beaucoup à cet appareil ou pas, si les têtes vidéo sont bonnes, etc. voila.

La mécanique ressemble un peu à celle de mon C9 F mais je n'ai pas ce rectangle noir, sans doute une protection supplémentaire comme il est portable.

Si tu étais près de chez moi je te dirais de passer avec ton Beta histoire de voir ça, mais je suis dans le sud, prés de Salon de Provence.

J'ai eu de la peine à trouver des réponses. Chacun me donne une piste différente.

Cette colle marron, je l'ai gratter sans avoir besoin de tout démonter. Mais ça n'a pas suffit.

Le problème est surement ailleurs. Dommage pour une machine qui semble presque fonctionner.

Il emmène la bande, comme il faut... Par contre, un peu de mal à réagir à l'eject, au démarrage.

Hi David

I am trying to find if I made pictures of this, because my SL-C9 F is on a TV stand with 11 other heavy devices (Betamax , VHS, Laserdisc, DVD, BLu-ray, HDD etc.) plus several hdmi and scart switches and a Samsung 75" led 3D HD TV on top of it and although it is on 5 wheels given the weight and the number of cables I hesitate to move it just to take a picture.

I placed the scart in the zone you describe but not at the exact place you mention because with all connections and wires around I wasn't sure it would fit. I think it is slightly under, but not sure.

I simply connected all 3 inputs and 3 outputs to the BNC/RCA connectors and it works fine. If I find a photo I will send it to you.

Anthony : cela ressemble beaucoup à la panne classique du hall effect sensor grillé car court-circuité à cause de la colle qu'ils mettaienr dessus (on ne sait pourquoi) qui a pris l'humidité ambiante et est devenue conductrice, cela se produit avec pratiquement tous les betamax Sony qui ont rencontré une zone humide un jour. Il faut complètement démonter le tambour de têtes pour le remplacer et ce n'est pas facile quand on n'est pas un pro, je l'ai fait une fois sur un SL-HF 950ES et c'est une des réparations les plus délicates que j'ai effectuées sur un appareil.

Tous ceux qui ont un Sony Beta devraient nettoyer complètement le hall effect sensor de leur machine en enlevant les traces marron qui recouvrent ses pattes et vont causer très bientôt le court-circuit, il est facilement visible par le dessous et on peut y parvenir avec un coton tige mais on ne peut pas le remplacer sans démonter et extraire le tambour de têtes.

I don't know if you are french, I am, anyway this will be a good way to pratice your french if you are an english man living in France :-)

Anthony,

The F1 machines are very well built but being portable and heavy can suffer if dropped. I have had trouble with a number of F1s that have breaks in the double sided boards. A lack of tracking pulse to the right parts of the circuit produce the problem you are seeing. There might be another cause but I would use a CRO to see if the tracking signal is present and gets where it is supposed to go. First make sure it is not just a dirty ACE head meaning that the pulse is not being detected at all in the first place.

regards Noel

Hi frandid I was thinking of the left hand corner where the rear cover, which looks like that piece can be cut out, how did you do it ?. I mean where did you do the connections and how many?. I also use freeview and do that by using the signal through the tuner.The other reason is My TV has not got a ariel input it has a large silver box which all the connectors run through, and I have not tried yet but ,I think I can use my sky Q or my HD box to connect wirelessly, and use the wireless connection from my laptop to use the computer input, and have the screen as input from the laptop.I am also embarking on using a old 1975 TV,of which I have 2 very good examples both work and there was one model which had a lift up lid which revealed a ,Phillips VCR,N1501,Iintend to use either a sony C9 or a 950. I am also looking for good used tapes,I can travel within a reasonable distance to collect as I use a sack trolley which ,I travel on the train with,maybe if you documented when you fitted your scart you could if possible mail me some photos,I did hover over your name your mail details did not show many thanks David

Hi everyone,

I found a Sony SL-F1 (secam version, I live in France).

Here's the video of the problem : https://we.tl/3lWJOK6mOE

Stops after 2 seconds (play or rewinds function).

I put oil/grease on the axe of the Reel Motor. I also removed the old glue.

The only thing I didn't touch is the Capstan Motor and the Video Head element.

I'm not a pro, I don't want to do mistakes.

Thank you

Unnix,

I have actually repaired at least three F30 /F60s with the broken last gear tooth problem. Better than wrecking another F30 for the rare spare.

They break because spring tension is constantly on them when the tape is loaded, the thickness of the plastic under the tooth at that point is thinner and the plastic becomes brittle over time.

This is how you do it. It is like the principle of doing a bridge in dental work.

Clean the part up to remove all grease from the gear and broken tooth

Plastic weld the gear back in place with a soldering iron tip (carefully)

Get a pin, the type used to hold seams when doing dress work and measure its diameter

Use a drill to drill a hole through the centre of the last tooth and the next one back from it

Bend the pin in a "U" shape as close to square as you can get it using small pliers with the sides of the "U" matching the space between the holes.

You may have to try a number of pins as some are more brittle than others and wont handle a 90 degree bend needed in creating the "U" shape.

Insert it into the holes of both teeth

Bend over the points poking through slightly (about 30 degrees) and clip off the excess just beyond the point so as to avoid it pulling out under tension. (It shouldn't as the bends should hold)

I can send you pictures of a repaired gear if you need them.

Hi David.

I put a scart socket on the back of my SL-C9 F a long time ago and it works fine !

But be careful, in fact there is only a précise place where you can fit it, otherwise you might have problems with some boards.

I have polished the folding guides that fit in the black plastic ..

I have also cleaned and polished the drum where the ribbon travels ..

By the time problem solved !!!

Now I have to apply the correct tension to the belt, both with the tensioners and with the RV002 potentiometer.

What tension is applied to the tape ???

I have a few left of those otherwise hard to get side gears that seem to get one broken tooth after time.

I can also service /refurb your domestic beta's (what models are they?) and SVHS Panasonic deck (model no). Is it the 'K' mechanism as I have l a lot of experience with their common issues.

The betacam maybe more tricky but I have successfully sorted one such machine out

Hi there, just found this site, brilliant.

I have taken apart my SL F30 as it was ejected/loading etc erratically. I found on the loading mechanism in the gears a tooth has fell off.

I am located in the UK (Stourbridge - just south of Birmingham), does anyone know of where I could obtain some new gears?

Also, does anyone know of a company that services all types of VTR equipment, from the consumer Betamax players I have (both faulty) to Betacam, and Panasonic SVHS editing decks?

Kind Regards

hello noel I did get your message both times I will try to reply later. I have just removed the DC-DC convertor from the C9 ,I recently got. I decided to take it apart and look at its condition.I decided this because there is no indication although I was told it had been replaced,althou there is no indication of how many hours or years since it was replaced.I also think bearing in mind how easy it is to change them rather than have it fail later.I would like to ask have you ever attempted to fit a scart socket to a C9 ? ,I think there is enough room and the input and output wires could be attached to the phono connections or their take off points.The reason for that is because 2 tv sets,I use are Sharp Duos ones, and the earliest one does not have a ariel/rf input/output plugs,this set works very well but has a large silver input box which the connections are fed into,after that the input to the TV is done using a large heavy duty ribbon cable,the tv works very well its, a 37 inch ,LED type.i also thinking of scart because the sky H D box and the sky Q system does not have rf /ariel output feed for the tv set.on the subject of TV sets,I am collecting a 1974 Dynatron ,CTV22A ,26 inch model in full working order with a very good tube,and a ultrasonic remote control,on Sat 23rd June,as before there is no rush for the required parts just yet probaly September time regards David

Isopropyl alcohol.For cleaning and soft materials for use to polish.

I wouldn't advise cotton buds either (as many do) as the cotton is totally unsuitable around the head drum as it will catch and break off those fragile heads.

I wouldn't advise that with the compressed air as I know someone who did that on his HF100 and one head was completely missing afterwards.

Also you can manually have the loading ring come out but don't put ANY pressure on the pop up guides unless they are locked in the black plastic slot at the top part.

They are easily broken at the base.

Okay!!

I will try to clean the path of the tape in the drum ..

Also polish the drum for the path where the tape passes ..

The guide posts only come out when the tape is inserted, so it is difficult for me to polish them.

The reproduction and recording are very good ..

Therefore I will try to clean and polish the parts of the tape path as much as possible ..

I can try to blow the affected parts with pressurized air,

It would be dangerous?? I never did it!!
