I think that's the Island of Misfit Video Formats...

Boby, reading back to your second-to-lost post, it looks to me like you're trying to play an NTSC beta-hifi tape in a PAL deck. You won't get hifi and, I'd imagine, no picture either. If you're talking about the same HF950 as the one from Europe (if there's not another Japanese model w/ the same number), then there's your problem. NTSC decks use the video heads to play and record the hifi tracks, also. PAL machines use a separate pair of audio heads on the drum to do the same. The SL-HF77 is the same as the US SL-2710 (according to http://www.betamax.to) so it's NTSC.

Madness:Nope mine is PAL ( SL-HF950E PAL) i record from PAL Tuner inside it.yes it has two audio head infront of the Drum (record and play)it can also Dubbing Video or Sound.Problem is BetaHifi light wont light up after recording sequence.But if i play the tape that was recorded in 950 on other machine then it is BetaHifi (the light in HF77K is ON)So what or where inside the HF 950 is the malfunction partsI don't have Diagnostic machine such as Osciloscope so i cant figure it out.note : ALL MACHINE ARE PAL.

thanks DasImperator and Brenda for your help with my query about the HVC-4000P. Judging by your responces I should be able to rig it up to the Fergusen Videostar 3v24 (VCR and tuner) that came with it for free. The VCR is a vhs and has a socket for a camera,, although not a 14 pin one like the camera. It has 8 or 9 pins. Do you think it worth my time trying to rewire the 2 together using the great pin diagram you supplied, hold out for a compatible Beta VCR on ebay or can I buy a suitable adaptor (if they exist)?

sorry to be a bit dim on these questions. this is my first venture into VCR's and I quite like the idea of being different and going down the beta route.

regardsrupert

I've seen adapters made for hooking a K-plug camera to a 10-pin socket go up for bid recently. THey might still be around somewhere but most likely you'll have to build your own - just make sure the Furgeson outputs to the right voltage (12v I think). That would mean you'll have to know the pinouts of the Furgeson unit. SL-F1 and SL-C9 Betas show up regularly enough on the European eBays that getting one shouldn't be a serious problem or cost issue if you wish to 'take the plunge' into Beta.

What would be a possible cause of the VCR recording black lines and white flecks for about the first minute of a recording, and then recording fine from that point on for a whole movie? Any possible leads? My best guess is worn heads. Any other suggestions? harrym

It could be worn heads or just dirty ones that managed to clean themselves on tape play...

Does this happen on every recording or just that once? On the same tape every time or in the same spot on a tape?

Might also be a back tension problem that clears itself once the tape is 'up to speed'...

just stuff off the top of my head...

It happens on new tapes or old erased tapes, same place every time but it lasts longer on some tapes -- up to two minutes. I'm going to take it out and clean it as soon as my new [to me] SL-HF550 arrives. Thanks for your thoughts. harrym

maybe the tracking head is dirty?

You mean Audio/CTL head??? I'd take the cover off and watch the operation... sometimes it will "Jerk" the tape to start and then it will even out, some slack traveling to the front and back and so on... this is why decks like the IVC-9000 have closed-loop capstan (Capstan on either side of the head to control speed)...

I'll watch it with the cover off to see if that gives me any clues. Thanks, all. harrym

Re Boby HF950. Could it possibly be that the HIFI audio record head is dirty/worn whilst the playback head is ok?

I'll edit that! What about a known HIFI tape from another machine or a pre recorded HIFI tape? If still no beta HIFI light then may be light itself is faulty.

Hi Have a Sony SL 750. the linear skate load of this machine has been great since i bought it in 1987. I have'nt used the machine much in past years ( possibly 8-12 times a year) . Anyway the other day i loaded a beta tape of old vacatons and it played fine. I hit rewind , then unload. Well for the frist time ever, the tape won't unload. All i hear is the motor tring to unwind and unload it. Does anyone no if it's a problem I fix myself ( I'm mechcanicly inclined, but never delt with electronics or VCR's in general) or does it need to see a VCR repair shop. thanks.....Mike

_@_v - i'm afraid that SL-HF 750 is too far gone... you'd be better off sending it to the Olive E Thomas Home for Wayward Betas...

actually it's likely a problem with the tape threading ring and/or it's drive belt. JSparkin's HiFi Beta page shows the innards of and SL-HF 950 (but manages to obscure the bit of mechanisim I'd need to see to tell you what kind of belt it uses)...

Hi,

Thank Olive for nice photos of the Sony SuperBeta Hi-Fi SL-HF77ES PAL!I'm fainted almost in the work, after I have seen the nice pictures of the videorecorder SL-HF77ES !Olive Thomas are myth!I have saved all the photos!

Between SL-HF77ES PAL and SL-HF77 Japan are wholly different! The videorecorder SL-HF77ES PAL is like SL-HF100EC, but it add SuperBeta, Quick Timer and 4 event program/3 weeks for timer. The program timer of the videorecorder SL-HF100EC is 2 event program/1 week and isn't Quick Timer.

Goodbye.Sergio

Mark:Olive:Sergio:Joel

I'd open all the wiring schemes in HF950 related and pull up the upper most Hall Effect sensor (upper side of the Drum)also disconnect the wire socket then Running the unit as normal.The condition is having the liniear audio out. It means that the Amplification block of the Rotary Head audio doesnt work as it should be. One step ahead of finding the problem.<<correct me if i'm wrong>>About the SL HF77K / SL HF77ES are almost the same machine except the 77K has microphone input.I'd already replace the HF77K Rotary head with the HF150 origin parts and it works as New Video.

Re: Harry's problem. One of the prerecorded tapes I bought at a secondhand store recently had that exact same problem. The first couple minutes were all snowy with no sound. I thought the tape was bad or worse, had gummed up the heads of my SL-HF600. I was desperately turning the TRACKING dial back and forth trying to get something when all of a sudden the picture came in, clear as a bell, with crystal-clear Hifi sound too. I rewound it with the same result. Just the first couple of minutes of tape were bad and after that it was fine. My guess is, since the beginning of tapes is under the most stress, since that's where the loading mechanism usually grabs it and threads it repeatedly, it wears out first. I've opened the cover flap of some very old rented VHS tapes and clearly seen two creases down the width of the tape, pressed in where the threading posts have pulled it back and forth repeatedly.

Another case of engineering against all logic. After years of designing ways to force heat out of a computer, some team creates a motherboard with on-board sound using a dual triode VACUUM TUBE. Idiots.

http://english.aopen.com.tw/products/mb/Pax4b-533tube1.htm

Well, hell, I'd buy one jsut to ahve a Tube in my computer. Not as much fun as a Nixie or Decatron, but, cool!!! (Well, warm actually). My dad used to work on the Air Force's "SAGE" computer which used thousands of tubes... the size of a football field, it ran at 3Mhz. Not bad...

and a Mac Classic could still beat it at 7mhz. 4 Game boys could beat it at 1mhz a piece....

Hmmm. Wonder if Apple would make an Airport base with one of the huge transmitter tubes? :D :) haha. Also, yes. I believe that the 950 is too far gone and should immediately be sent to the Wards home for some emergency treatment. Hmph! Damn it, as soon as opportunity for cheap autoBetamie appears, some snail slaps their pod onto it. Eee hee hee! A tube mainboard.. Wonder how fast it runs at. With my luck it will support Pentiums only. Ach! I've lookd @ the tape of a 1986 VHS rental tape, and ugh it was in deplorable condition; the tape has faded to a grey, and you very clearly see the head wear in the middle of the tape. At some parts of it you can also see the 4 lines on the top of it like the VeHos drum has. Too bad the Spamsung ate it during its last hurrah. Went into the trash. Hee hee! I want a pro 8amie!!! I just want to find the one that looked like the Betamie prototype. Olive has a piccy of it; it looks like a huge version of the MicroMV camcorder, or JVC's horrid MiniDV one.

SAGE (SemiAutomatic Ground Environment) was around since the 50's. It was the peak of Tube technology in computers. No Mac classic in the 50's... The SL-MV1 could pass as 2nd cousing to a Mac classic and the Vectrex as 1st cousin...

What are those two? The Mektrex and the other one...

haha shows how stupid I am.. cant even remember a name for 1 minute..

The SL-MV1 was a car-console type Betamax player with a TV in it, built around an SL-B5... Very cool unit. The Vectrex was a video game that used a vector display, and could make some pretty realistic 3D Images using a headpiece...

Olive,If you've still got that reel drive motor for the SL-2000 that'll work in my SL-2500 please e-mail me .I need the whole payoff and takeup mechanism including the small circuit board that's attached.The circuit board is the problem why The reel motors aren't working. Thanks so much!

HEY NIGERIA SCAMMERS! IF WE'RE SMART ENOUGH TO USE BETA, WHAT MAKES YOU THINK WE'RE DUMB ENOUGH TO FALL FOR THE NIGERIA SCAM!!!

Gee, I saw that vacuum tube motherboard somewhere myself. That got me a big laugh and the same thought crossed my mind: "Would this add complications to system cooling?"

OK: How about a custom hybrid beta using tubes in the video stages and hifi audio stages? Then maybe w/ Nixie tubes for the H/M/S counter display w/ Dekatron tube for 10th seconds? And, of couse analog VU meters (á-la SLO-1700 /1800).

Sony's Earliest Videocorders (EV -200 /200R) were tube-type. The UV-340 (Boy, did Sony overuse the 340 model number... SLO-340, SL-340, UV-340...) had an LTC but the display was not a nixie, it was seven individual Grain-O'-Wheat bulbs! believe it or not!

Yeah I still have a couple SL-2000 reel drives if you need one. Just cut the .n¿spam and replace the remaining ¿¿'s with oo's in Yahoo.

Looks like those Nigerian fuquers have figured out how to sleech disquised e-mail addys...

Maybe GW can swing by Nigeria on his way to or home from Iraq as long as we're bombing the crap out of places that bug us...

Shouldn't be a hard sell as Nigeria has an oil industry...

Not that a war for oil is necessarily a bad thing. In the 1700s Holland and England fought a war for control of the nutmeg supply. The Dutch won but England got New York in the deal...

boby: if you have the schematics, why not buy a cheap digital voltmeter to check all relevent voltages? however, i suspect you need to replace your dedicated beta hi-fi heads. mike:amoungst other things, bad output gears on the loading motor can cause that kind of problem. i don't believe there are belts in the 750. if you replace the gear, the threading ring must be properly positioned with respect to the chassis.

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3008892966&category=15099 someone's tryin to be tricky, theres no lights on on the VCR.

Dumba**. I'd hate to be the sucker who bids on that. My RM-E100V came today. How's that Xerox of the manual coming, Sean? My R5 is in the repair shop right now, it arrived with the "half-load arm stick" that plagues essentially every Sony VHS mechanism ever built, plus a few other minor mechanical problems, and an annoying problem wherin the red and pink areas of the playback picture would bleed into the surrounding picture.

haha! That's an excellent ploy. Just say that the display drive failed! Heheheheh I might be tempted to do the same thing with my unRealistic beta-crap that I have.

That's not necessarily a scam item.It could be that the flash washed out the display. Or the he opted to photograph it in front of a turned on TV for the picture...

There is a design fault in the SLV-R5 power supply which causes the voltage applied to the color circuits to drift, and that's what causes the color bleeding.

Bob, you don't seem to know what you're doing. The 950 is a great machine, I suggest you take it to a qualified technician instead of fooling around in the head drum and possibly (eventually) destroying it.

The tube in this board is far from the CPU which is where temperature is critical. I'm pretty sure the AOpen engineers already thought about heat concerns in their designs. I hate to read the word "idiots". Nothing presses you to get this board anyways.

I'm pretty sure hes tryin to pull something, cause I used to have one of those. There's lights all over them when they're on.

Also, I'm on a horribly limited budget of about 100 dollars, and I need to buy something like an SL-HF900, 750, or 1000 for the editing capability. If someone would like to be incredibly generous and sell one to me I will send you either my Sanyo VCR4030, VCR4400, or Sony SLP-305 along with the $100. Marcus

My SVO-140 had the same problem. My local TV tech fixes it instead of swapping the parts. It makes a little noise but since it's not just another plagued part it will alst much longer. He know's what he's doing. So does Boby, it seems... Anywho, that does look like a scam job on that VCR to me... I thought someone else had an unblemeished RM-E100V and was doing photocopying... mine is all scribbled up!

meep! My 300 has a perpetual vertical "ghost" line on the mid-left of the piccy. It does this to all recordings...

Could someone please tell me if their is an adapter that one can get that will allow me to play beta tapes on a vhs machine? thanks

Nope, never was, never will be. Just buy a Beta.

Even though the tape is the same width (1/2"), and even if there was an adapter that could make the smaller Beta cassette physically fit into a VHS VCR (kinda like a VHS-C to VHS adapter) the VHS video head wouldn't be able to play the tape because of techical differences between the formats-different slant angle of the video track, different tape speeds, different video signal frequency, etc.

NO adapters... When will people learn. Beta tapes are DIFFERENT from VHS tapes in MORE than just size. they are BETTER than VHS. Just like you cannot play a CD on a phonograph or take a CED out of its caddy and put it in a laserdisc player, you CANNOT play a beta in anything but a Betamax VCR.

Flytippet: Around our shop I (almost) always preach "The engineers are not idiots. They designed it that particular way for a reason - leave it adjusted to spec." Of course then an official modification bulletin arrives. However it takes certified idiots to miss a long list of reasons why this bumblebee should never be given a chance to fly.

(1). Using a vacuum tube with a plate voltage over +150 Volts in an ATX design would put the bottom of that tube socket about 3mm from lots of grounded metal. Or did they invent a new 9-pin tube socket using modern surface mount technology? That thought is worth a chuckle to us gray-haired guys.

(2). ATX power supply voltages are no higher than +12VDC.

(3). Filament heat with conventional cooling will raise the infernal (sic) case temperature beyond its design. That heat will find your cpu sooner or later. Maybe you would run your computer with the sides open but most don't. These boards could precipitate a rise in P4 chip warranty RMA's (especially in Arizona), and eventually a disclaimer from Intel.

(3a). That 80-conductor ATA-100 IDE cable will droop closer to the hot tube every day. They never stay put even if you staple-gun them up.

(4). With the sides on it's hot and who's gonna know how nice it looks? With the sides off it's fragile. ("Daddy what does fragile mean?")

(5). Read the manufacturers web info on this thing. The spin doctors in their marketing department suffered dizziness trying to explain how its limited audio bandwidth and high THD specs are a good thing. http://www.aopen.com/tech/techinside/Tube.htm

(6). Every set of half-decent speakers out there features built-in amplifiers, often without a bypass switch. Let's see some amplified speakers with a glowing pair of KT66 or 6L6 tubes on top. That's what the idiots should have built (more people bought iMacs because the outside looked great than any other reason).

I didnt think there was any belts in the hf950? hmmmmm I could be wrong but I dont remember them in the 4 or 5 units I have broken down into a bench of bits.

The hf77es is a re-vamped HF150 - its completely different to the HF100 in all aspects. It does have some internal differences from the HF150 as well including a few boards. It was brought out with the HF99 with matching colour scheme.

Please dont call me sparky ;)

I have found a new hobby, collecting 12xx series CRT and LCD projectors so I only check this board about once every 3 months so drop an email if your after anything! :)

Back on topic (is that possible?) My SL-HFT7 has developed a habit of eating tapes just after I rediscovered the guys who used to do Sony's warranty work in this region in the 80's. They still do, but they say mine is out of warranty now. When it comes back perhaps they might find themselves recommended to be added to the list of places which still fix Betas...

http://www.palsite.info/directory.html

nnils:

There have been in existance tubes with 12 volt anodes (plates) since the 1950's. Car radios used them in the transition between tube and solid state. The radios using these tubes used a PNP Germanium output transistor, but used tubes for all the small signal applications. Another factor of these tubes is they had a much lower heater current, therefor a lower running temperature. I imagine that they have resurrected this technology. Wish I could remember those tube numbers.. maybe I'll have to dig through one of my tube manuals to find them.

Here we go...

Why oh why did Sony never deign to release linear stereo Betas for the US market? Despite the limited frequency response it would've been nice to be able to audio-dub in stereo...

There's a the SLO-420 & GCS-50 w/ linear. S'all I can think of.

And they all sound like excellent candidates for the Wards Home. :)

My SLO-323 has linear stereo, as does the 325 and possibly a few others. My JVC BR-6400U is a linear stereo VHS deck and the audio is NOT muted in speed search (Which it has at up to like 5 or 6 times, infinitely variable speed, too.) It's actually quite nice for a VHS deck and, being a true pro-only one it is built like a tank.

(Actually, quite a few VHS tapes are linear stereo. I have a "Pink Floyd" concert that is that way, and even has Dolby on the linear tracks. (Yes, Pepse, the tape I dubbed for you, but you got a HiFi-to-HiFi dub, and, sadly, the wall live was an ex-rental and is quite torn up. I intend to copy it to Beta, and once more to VHS for a friend of mine, and then dispose of the orriginal. The tape itself is damaged. Let me know if you still want a copy)

Thanks for the info on low-voltage vacuum tubes, Brenda. The only ones they let us play with in school were capable of quite a good zap. Seems to have permanently affected my hair. I still think any IDE cable would head straight for the tube, though.

I was referring to consumer-grade linear-stereo Betas (with built-in tuner and timer) that Sony seems to have denied to the North American market. Except for the Sanyo built Marantz there don't seem to have been any linear stereo consumer Betas...

Yes, they denied several features to several markets. The UK got linear stereo and BNR, the US got three speeds, Japan kept all the goodies for themselves and gave us... The talking VCRs. Geeeeeeee....

Why do you guys care about lowly VCR's with linear audio, like SLO-340's, and other old Beta equipment? Is it because you can't afford the real thing ? Like a SL-HF1000? Oh Wait,gosh. I am incorrect here. I too, appreciate the 70hz-10khz frequency response that most VCR linear audio has to offer. Heck, give it to me in STEREO. The pleasure is double the better in STEREO. Twice the low-fi noisy audio pleasure. Hmm, let me hook this machine up to my 1976 RCA XL-100 Colortrack TV Set. There it sounds just fine now. Just don't hook it up to the ol' HIFI now Marge! Grumpf.

I think all of us here have at least one Beta HiFi. I for one personally possess 5 of them, but we're just sort of lamenting the fact that Other countries got Linear stereo with Noise reduction while we were still using mono. I'm sure we all understand that linear stereo is not as good as Beta HiFi (hell, nothing I can think of off hand is as good as Beta HiFi) but it's just another feature we want.

Hey, ya never know. Might sound good lol

_@_v~ pblpblpblt!

Well since you're asking, I happen to have two HiFi units and two mono units myself.

SL-HF 300, SL-HF 360, SL-2000 and SL-5800

Both of the mono units incedentally have audio dub capability. Much as I appreciate HiFi, you can't do much(any) editing work with it so it would've been nice to have a consumer model Beta that also let you dub the linear track in stereo (would've loved a stereo recording Betamovie camera as long as I'm wishing for stuff that's never gonna happen).

Yeah, or even a stereo recording portable. In real television work (In which I have some small experience) we make use of two linear tracks so that one can be, say voices, and then we can dub in music or whatnot on other track, and then mix down to mono for broadcast. That way we have two distinc tracks to work with like the layers in photoshop.

doesn't the slhf1000 have linear stereo?

Nope.. the linear audio track is monaural.

sparky: hate to burst your bubble but NOBODY said anything about belts in a 950 ! i was only politely rebutting olive's assumption there were belts on the 750. i have both the service and operation manuals which reveal no belts at all. they're quite helpful in in making repairs so none of my 750's wind up broken down into bits on MY bench. once you learn to read posts properly you might want to slowly progress to service literature. then you may want to buy a vom,logic probe,logic pulser,frequency meter,and dual trace oscilloscope.

Joel,

This is a hobby page and John (not Sparky) made a valid comment and even said he might be wrong. He only made a comment because I emailed him Olives comment about his site and he noticed that she mentioned a belt. Perhaps you should read it more closely yourself. Having a go at him is not in the spirit of the information you read before you make a post on this site anyway. I can tell you that he has a CRO and fluke "lab reference" voltmeter and lots of other stuff. He also has service manuals. Funny thing is, I have to pull machines apart to fix them too. But, does that really matter? You don't really have to be able to fix beta machines to have them as a hobby. Anyway, read the following!

regards Noel Higgins

_@_v - I was referring to the bit of mechanism that loads the tape around the head. On most Betas that is usually accomplished with some sort of loading belt. Either the belt links to the tape carraige (to suck in or spit out the tape) like in the SL-HF 300 or like the SL-2000 and some of the industrial betas like the SLO-1800 actually links the motor to the gear train assembly.

Of all the SL-HF 750 or 950 pix I've been able to find, only JSparkin's piccy shows the inside of an SL-HF drawer-oader Beta. However in both instances the part I'd need to see, in order to confirm the design of the cassette loader, is obscured.

If someone would kindly send an SL-HF 750 to The Olive E Thomas Home for Wayward Betas we could settle the matter once and for all....

And if someone would send a Millenia S with snow flake pearl white mica exterior and tan leather interior, a pallet of L-830 Dynamicrons and a SL-HF1000 to the Wards Home For Wayward Millenia S-es and Outcast Professional Video Equipment, we could call it a deal!

SONY C6 PLAYBACK PROBLEM

Hi,

I recently bought a secondhand Sony C6 betamax vcr and have a problem during playback. The picture rolls slightly and there is some screen noise occuring every 5 seconds. In fact with the lid off it sounds like there is a temporary slow down in a motor somewhere. I have cleaned the heads and checked the transport mechanism and these seem fine. The picture is very good. I have read somewhere that it might be a capstan motor problem or poor capstan lock. Has anyone had a similar problem and could point me in the right direction?

Any advice would be helpful.

Thanks!

On the system servo board there is a pot labeled "CAP FREE". You will only have one because PAL-only machines are single speed. I cannot direct you to it because it will be an entirely different sytem servo board. You'll need to adjust it a little, with the machine running. It does indeed sound like you are having mild off-speed problems... My only other guess, which you may want to try first, would be perhaps the pinch roller has a dirty spot and looses its grip on the tape... clean the rest of the tape path.

well I'm tempted to say a trunkful of BVU-800 u-mies but that'd be ONE. LOL.....

Then you're not familliar with imperials. A trunkfull of BVU-800s would be at least three in an Imperial, maybe four... and an Imperial could crush a Mazda and it wouldn't know it...

Olive,

That's fine, you made a reasonable assumption. I checked the service manual and definitely no belts in the 950. Because of the sliding load tray they use a different design. I took a 950 that's needing a bit of TLC, out of my "beta heaven" rack and checked it out. It uses a small DC motor with a worm drive to drive a number of gears in the same plane as the load ring. It has a white plastic cover over the top so you don't see much but you can see and lubricate the worm drive easily from the RHS of the tray. I must admit, when I have fixed these things, the problems have been drum motor, reel motor, power supply or head/tape path problems so I never looked that close before.

cheers - Noel

SONY C6 BETAMAX PLAYBACK PROBLEM

Thanks for the advice - one thing I forgot to add is that I can pause the tape but it will still be affected by the problem every about 5 seconds. This would point to an electronic problem I think.

Cheers

Are there any Betamax VCR's for sale?

Depends on where you are... I think Brenda Ann has got some NTSC units available but you'll have to speak with her on that matter... The universal answer to that question is "the 'Ebay' website for your region of the world". Beware of high prices...Brief list of models that are reccomended(NTSC)SL-HF-900 most common machine, arguably one of the best.Sl-HF-1000 costly pro-grade edit deck... Very nice unit if you can lay hands on oneSl-HF-750 Good three-speed machineSL-2500 Mono deck with lots of featuresSl-20 inexpensive and rugged. Extremely high quality of construction in this one.(PAL) SL-C9 stereo (not HiFi) Deck with lots of nice features SL-HF-950 Has "pro" mode optomized for "Pro-X" tapes... Very saught after, however. SLO-1700 Industrial deck. Extremely well built.

Shamus,

C6s have a design problem here that makes them worse than most others as the componenets age. If your C6 picture still rolls every 5 seconds when the pause is selected then its probably a drum servo problem. The manual says put the machine in record mode (of an off air program will do) measure the voltage at TP2 on a CRO and adjust RV9 for 5.1V For the capstain free speed, in playback mode use a CRO or voltmeter and measure TP5. Adjust RV3 for 5.5V (+/-0.3V)

regards Noel

noel:point taken. perhaps i should have substituted the word "I" for the word "NOBODY" for the sake of clarity. the first 2 sentences of john's post,however, do appear to direct sarcasm at my apparent equivocation on the presence of belts on the models - hence, my response.

I have an SL-2700B Betamax for sale, this one had the loading mechanism issue fixed. It's been exceptionally cared for and I am the original owner. I'm selling it as a parts deck because you cannot FF or REW while in play mode without it cutting the tape. It is completely functional otherwise (including non-play mode FF and REW). I believe I have the manual and remote for it too. I'm on the west coast, USA and want $25 + shipping for it. The motherboard, functioning load mechanism and video head alone are easily worth the $25.

I am 'crxtrader' on eBay. I have 63+ feedback (no negatives) on eBay, and I can provide a screenshot of my "myEbay" page upon request for verification.

BTW, if there's a lot of interest in this SL-2700B deck, the highest offer wins.

Everyone.

Though this is not related to Betamax's I have to mention this as it's important.

My mate Doug in Victoria Australia whom has a collection of vintage video equipment is getting rid of three 2 inch Quad VTRs as he needs space for some LMS machines. As there's virtually no marketing in 2 inch VTRs he's going to get them destroyed for scrap metal unless someone is willing to take them off his hands. The 2 inch VTRs are: RCA TR-61, RCA TR-70 and an Ampex AVR-2 all in PAL format. These are very few remaining 2 inch quad VTRs left in Australia.

Anyhow I was wondering if anyone here is interested in these VTRs or know of anyone who is interested in them? If so then here's Doug's email address for you's to contact [email protected] . Also contact me too at [email protected] or [email protected] . I'll be asking around on various message boards and groups and emailing various video companies to see if I can find anyone who's interested as well as I desperately want to see these VTRs go to a good home instead of being bulldozed and used as scrap metal.

Lastly a few things to mention, the suitable environment for these machines would be a room with a tiled or carpeted floor and air conditioning is preferrable too especially in hot weather conditions. Also Doug uses 60 psi of absolute dry compressed air when operating these VTRs.

Well then Sean the Millenia isnt as tubby as the Imperial and can accelerate faster.. Plus has airbags and traction control.

____@_**~ plhllhppphhhth!

WEll a friend of a friend of mine would be interrested in those big decks but unfortunately a: he's broke, and b: he lives in Nevada...

That 2700B sounds like it might have a badly nicked head if it "Cuts the tape" in betascan... I'd get a few sacrificial tapes and see if I couldn't polish the head down somehow... You'd need what's called "green tape" that polishes the heads, but the tape from a dy cleaner should work... of course you run the risk of wearing down the heads but it's better than having a deck that destroys your tapes...

Jesse: most Imperials since the 50's have had a 440 "Hemi" motor... don't underestimate them...
