HF950 on eject it leaves a loop of tape out of the cassette I have raised the motor rotor to stop it rubbing on the coils which look ok. The tape rewind seems lively enough but it stops too soon leaving the loop of tape.

Seems like you have no forward reel pickup tension there at all. You can make the mechanism load without a tape to see if the pendulum drive is engaging properly as well.

It will still cut out after a short time but you can see if the pendulum arm moves freely to engage. The drive action for forward pickup is different than for fast forward. Don't rule out the pendulum arm as a possible issue. Some of them have the end bend up and snag a spring.

I have a Sony SL-T30ME.

The transport works fine but the video is very bad.

I guess the rotary drum heads need to be replaced.

Any one knows where to buy the upper part that has the heads or the whole drum?

My husband and I are looking to part with a dust covered collection of more than 1,000 uncatalogued beta tapes, 5 beta players (Sony and Sanyo) and a high speed rewind as well as a"still in the box" Sony Betacom. My husband is a retired media professor who had viewed the Beta format as superior to the VHS format when these recording media were introduced. He persisted in his commitment to the Beta format over the years and acquired quite a collection of tapes and players. He was often offered holdings from rental stores that were de-accessioning beta tapes and he purchased Beta machines for his students to use to view them. He made use of many of the classics in his lectures and circulated films of all sorts for his students to analyze as class projects. He must have made good use of them as several of his students have achieved considerable acclaim as film makers. Some have received Oscars, Golden Globe Awards and Emmy Awards from USA professional organizations. Please advise as to anyone you know who might be interested in these items and note that we would like them to be taken as a single unit if at all possible. The collection is in our home in Pennsylvania USA, close to Philadelphia.

Hello everyone,

After a couple of years of working on Philips VCR machines, I have a Beta challenge to solve.


I have a lovely Sony C20 that has an intermittent fault. All functions are fine except on-occasion, unlace is leaving tape loose in the machine. This only seems to happen if PLAY/FWD is in use before the eject button is pressed. It is also much more frequent a problem when the machine is warm/has been playing tapes for 15mins+

Interestingly if I get the idler to be on the supply spool when eject is pressed, the problem doesn't occur.

I have oiled the lacing ring AND the supply/take-up spools plus checked the idler - seems to flip about with ease.

Any ideas? I've seen this on the Sanyos but not on the Sonys.

Hi again,

Apologies didn't read the tech pages properly before my last post. Do you think my issue is dothe first and last repair tip listed on the C2C20 page? I assume the safety resistor and transistor mentioned are in the SS servo board ?

Thanks, Betaboy.

I have a C6 Mk2 ready to take apart and only have Mk1 belts.

It gives me confidence to know the belt set is the same.

Hi everyone,

First time poster... just getting back into the wonderful world of betamax.

Does anyone have the service manual for a Sanyo VTC-6500?

In particular, I'm trying to locate the DOC preset pot on one of the video boards.

Thanks in advance,

Hi again!

Or, alternatively, it someone has a suggestion for where I could purchase a Sanyo VTC-6500 service manual that would also be great.

Happy to buy it if required.

H Gavibeta:

The DOC for the VTC 6500 is located in the head amplifier can NOT on the boards.

You can access this by pushing the two black tabs at the top part on the back panel section that has the VCR serial number on it.

You do this from the inside after removing the top cover.The DOC is the bottom hole in the silver head amplifier can.

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

Rob :

Two things to check...............Make sure the gear on the pendulum is free and not sticky.You can add a tiny drop of oil to the shaft on that if so.

Also at the end of the plastic pendulum arm that houses said gear ,make sure there is'nt a slightly raised lip as that has been known to get stuck at times on a spring when trying to unlace.Not all have this extra 'lip' so it can be removed if so.

Kevin, you're a star mate!

Thanks for the tip and the access instructions. Think that board is called VP-1 (Video Pre-amp).

I'll take a look later today.

I've acquired a Sanyo VTC 5000 and would like to start by replacing the belts.

Can anyone point me in the direction of finding out the exact specs of the belts; diameter, thickness etc?

I have a Sony Betamax SL 8000 video recorder from the late 70s and just wondered how collectable it is.

Itís in working order and actually had a new recording head fitted just before we stopped using it in the early 90s,it has been boxed ever since.

Moonman - The belt kits are available on eBay for a few pounds.

I have one of these lovely old machines that I've just serviced using Colin M's great video on YouTube, however, the machine played for about an hour before slowly dissolving into black and white.

Occasionally it does show very distorted colours and strong vertical blocks (five of them) up the screen.

The picture is sharp, just black and white - suggestions, please?!

I have a Sony SL-C9, the very first VCR I bought in 1982. It is an amazing machine and far too sophisticated for its time or even now. I made my first student film in 1984 on the SL-C9 by hooking up a video camera to the front socket. I am now a professional documentary maker. With the advent new digital techonolgy, the Betamax recorder got little use, but I was so fond of it, I decided to keep it. It's been sitting in storgae for nearly 30 years. Now I need it to solve a mystery about a 1985 Channel 4 documentary which I recorded off air in 1985. But have hit an obstacle. The tape loaded, and nothing happened on pressing play. Nothing happend on pressing eject. I mamaged to finally get the tape ejected, sadly with a litle force. No damage to the tape. But the de lace and eject mechanism is stuck. On pressong eject, I hear some de lacing noise and then a rattle, that sounds like gears not engaging properly. The fault is mmechanical. Broken gears? Belts not working properly. I don't dare touch anything.

I know I can buy a working SL-C9 on eBay, but am fascinated by how we can get this one working.

Any tips? If you can help you will contribute to solving a historic puzzle!

Thank you

Apologies for all the typos in the previous message. I was typing fast because of the excitement of finding a Betamax fan community!

Ok, so not a PAL vcr but I've recently come into possession of an NTSC Sanyo VCR7200 Beta hi-fi vcr which has a colour output problem.

The output is in black and white but very often a vertical rainbow effect of colour stripes come up on the screen, often in pause and picture search modes. The TV's I've connected to the vcr are capable of displaying NTSC signals, so it's not a TV problem.

Is there a trimmer capacitor or some sort of potentiometer on the video board that might cause this? I can't seem to find out any 'usual suspect' problems online for this model like we have in the technical section on here.

Thanks in advance 😌
