Hi Lorraine.

You found us then.

If you hover over my name my e-mail address is there.

We can discuss the VTC 5000 there.

Hi all,

Could any of you tell me where the internal tracking adjustment pot is on a Sony SLHF100UB please?

Many thanks,

Rich.

Rich

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

It should have TRACKING on it next to the pot.

Ah brilliant,

Thanks Kev!

Cheers,

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.

This is probably a long shot, but does anyone have a working capstan motor for a Sony SL-HF860D NTSC beta vcr for sale please?

Thanks

Rich.

Hi all,

Regarding my post for a capstan motor for an ntsc sl-hf860d, I think I've found the cause, the drive ic may be faulty, so I've sourced some new ic's from Italy, if that doesn't cure it then I have a contact in Australia who will supply me with a capstan board.

Anyway,

The purpose of this post is that I've been given an sl-t7 and two sl-c7 vcrs. The t7 did power up and sort of fast forward, rewind etc, then I heard something pop inside. I've checked the glass fuses on top of the psu and they're ok, but the VCR is dead. What should I check next to get the power back please?

Also on one c7 the picture shakes side to side and the colour comes and goes, it's like the tracking is all over the place. I can't seem to hear any wobble on the sound. I've looked at the technical page for this model and just wondering if those two electrolytic capacitors on the servo board might be to blame?

I'm relatively new to the c7 so I'm not sure what to check for. The belts in it seem fine, with plenty of life left in the rubber and they're all quite tight and 'grippy' as new belts often are. Also the red timer led comes on when the VCR is turned on by the chrome coloured button above it.

The other c7 doesn't load the tape around the head, I don't know if it's a belt driven operation or direct motor as I can't hear any sort of motor turning at all (probably I'll use it as spares for the other c7 if I can get it working properly).

Any suggestions would be appreciated.

Thanks

Rich.

Hi Rich,

Sounds like the usual common problems with the C5 / C7 /T7 range.

The 'pop' was probably C10/C11 in the power supply dying. I believe they are 4.7uF 350v elcos. The originals were only rated to 85c which I guess was a mistake by Sony in the day. Use some dec my 125c ones. You may have now blown the switching transistor in the syscon board Q25. Check the t chemical pages on here.

The horizontal wobbling and tracking- like issues are almost definitely the light blue Sanyo tantalum caps in the servo board (AY6 board?). Open the bottom and unscrew the 7 silver screws that hold the bottom boards in place. Don't touch the red screws . The ones you need have arrows pointing to them. Push the board back and it hinges up. There should be 3 Sanyo tants. All 35v , 1uF, 0.33uF and .47uF. Replace them and you should be good

Regarding Lace up, you may need new belts bit first try with no tape. Cassette lift down with power on, standby off. Press the switch inside the lift on the left - this fools the machine into thinking a tape is present. If the lacing doesn't start, push the lacing ring by hand whilst holding the cassette present switch. Sometimes I push the lacing ring all the way round by hand then power on and let it unlace. Basically 30 years of sleep has made it stuff.

Good luck

Were these machines from Sean in Hitchin by any chance?

oh.. and excuse by (forced) spelling mistakes. The joy of using a "smart" phone on a long-ish post.

Hi,

I have acquired a Sanyo VCR7250, which is a US-sourced Super Beta. Thing is, it is missing an idler motor and idler assembly (!).

I would like to get this machine going, as here in the UK, it is actually quite hard to do (decent) NTSC beta transfers, and it's the only decent US model I have seen in the UK.

My question is this: - does anyone have experience of this model? A service manual would be fantastic. Failing that, does anyone know whether idler motors/assemblies from any UK/European Sanyos would fit this model?

I have lots of spares, so surely this must be possible. Otherwise, the machine looks in good shape.

Rob

Hi Rob,

Thank you for that reply and the information on the vcrs.

I looked at the technical information page on the c7 but I couldn't see what value etc the tants were, so I'll have a look online and try to find some to order, I also think I read that 2 electrolytic capacitors need to be replaced in the servo too?

I'll see if I can get that c7 with the picture wobble working first, then turn my attentions to that t7me.

The other c7, I've tricked it into thinking a tape is loaded, had to hand push the loading ring around the head, it didn't play or rewind, but fast forward worked. The loading ring doesn't come back round on it's own as I have to bring it back round to the eject position by hand. I also noticed that the record sensor cassette switch was bent out of the way and it seems to be jammed into the record over anything mode. It seems like it's been idle for many years.

Yes, they were from Sean, I got some Ferguson piano key vcrs too, but they've basically rotted and rusted away from the rubber feet on the bottom metal panel right up to the top lids. Shame really.

Thanks again for the reply, and I hope you get your US beta fixed up soon 😉👍

Cheers

Rich.

So just to confirm the tantalum values... 1uf, 0.33uf, and .47uf all 35v? Didn't know if the .47 might have been a smartphone typo instead of a 47uf or 0.47uf? Stupid phones. Haha.

Thanks Rob,

Rich.

Hi Rich,

Definitely 0.47uF 35v. I tend to use CPC farnell who have them all.

Good luck.

Rob

Thanks Rob,

That's excellent.

I'll take a look on that website in a mo.

I'll let you know if it cures the problem, fingers crossed as I've never ever had a fully working c7 before. Haha.

Cheers

Rich.

I've made some progress with the C7.

I've changed the light blue Sanyo electrolytic caps for tantalum caps as the tants are specified in the service manual.

I've got the picture and colour back without rolling and wobbling, but the sound has a very noticeable wobble on it. I've also noticed that on most of my pre-recorded tapes that I've tried in it the tracking wheel has to be turned halfway to the left to get a nice clear picture. The factory sealant green paint on the audio/ctl head hasn't been tampered with.

I had a thought that the capstan motor might be failing causing the sound wobble??

Is there anything else I can check to rule out the motor please?

On its own recordings the sound isn't being erased from the previous recording but the picture is being recorded fine apart from a vertical dancing band of colour going across the top half of the screen throughout the recording. It's not present on tapes recorded on other vcrs.

Any thoughts or suggestions in these faults will be greatly appreciated.

Thanks everyone

Rich

Hi all. I have 2 Sears portable Betamax VCR's, both with the capstan belt literally dissolved. Looks pretty tight to get in there to replace this belt. Any suggestions on how to go about this; more importantly, what kind of belt does this take? Thanks much.

Hi all,

I have recently purchased a Sony SL-C6 MkII from ebay, all good so far!

The machine loads tapes and tries to play but then just rewinds and spits them back out. any ideas on what could be the issue and could this be coaxed into life?

it sounds like something is either slipping or jammed, but as i am not familiar with a fully working betamax player, i am a bit lost as to what to look for.

all the belts (that i can see) seem to be in decent shape, (none of them at loose or snapped)

if i hit the play button as it is still loading it tries to play, in fact, it did play before i could connect it to an output, i managed to get sound out of it before i could get video, but now i cannot get either.

any assistance would be greatly received.

Good evening,

In October 2017, I asked a couple of questions about converting a Japanese market SL-HFR30 to 230V, and I promised to share my progress with this forum. It is now more than a year later and I was finally able to purchase a machine for parts (I didn't want to part out a good machine, so the search took a bit longer). I have replaced the complete PSU with one from an SL-30, all the connectors are the same and as I already assumed the only difference is the transformer.

I just played a video: the image and sound are good, although the sound seems to be a bit soft. The machine itself is a bit noisy, at least compared to my SL-C80. I think it would benefit from a cleaning, after all the machine is older than I am!

I have an sl-8600 beta vcr 1979 can anyone send me an pdf jpeg copy of the manual please? Thank you
