UPDATE ON SONY SL-P8800R (Super Beta Player)

-

Kev/Fivos/Noel,

I think I am accumulating problems here. I now seem to have 3 problems and not sure whether the last 2 are related

1) Very bad dropouts on playback

2) Capstan running too fast

3) **NEW** Failure to lace.

Following Fivos' advice, I looked at the SMD caps on the Capstan Motor Assembly. *** 2/3 were open circuit ***. Replaced with equivalents.

But... before I could prove that was the issue on problem 2), problem 3) has occurred.

I have taken some video ( https://youtu.be/CyuzSv9Dtcc ) which might tickle someone's memory and Noel has sent me some scans of a similar Beta service manual which I will look at today.

To summarise problem 3).

- Tape mechanism loads, capstan spins clockwise for 1/2 sec, then anti-clock for 1/2 sec. Threading motor moves backwards (?) for a split second, then forwards (clockwise) for a split second, then aborts. Tape ejects.

- I have manually turned the corkscrew drives (with power off) to prove the loading ring can lace correctly with no obstructions. All okay.

- I have unplugged the capstan assembly to see if if problems 2) and 3) were related. With Capstan assy unplugged, the lacing problem still occurs.

- I am not sure what voltage rails are supposed to be present on this machine, but the power board appears to be providing +15v, +12v and +5v . All rails are steady.

Any views on how to approach this new lacing issue?

Do you think the Capstan too fast and this lacing issue are connected?

Thanks Noel.

Looking at the external pictures, my Super Beta player does indeed look like the Australian model you refer to.

Let me see if I can get the Capstan issue fixed and I'll be in touch.

Regarding the DOC - I could not locate the usual pot marked "DOC" on my main board. Would be interested in comparing mine against any service documentation you may have.

I will ping you

Rob,

On the SLS2000 VS17 board there is a drop out compensator adjustment and it is RV203. There is a voltmeter setting procedure to set it up.

I could take photos of the relevant circuits to see if you can track down your capstan circuit issues.

cheers Noel

To Rob further down the page about his rare PAL beta player.

The mechanical construction seems very similar to the SLS2000 super betas we see in Australia.

They were a lot more plastic and hence a lot less reliable in the long term.

See http://www.palsite.com/sls2000ovi.html

I have a poor photocopy of the service manual but who knows how close the detail is to your unit?

You can monitor the video head waveform with a CRO on VS17 board CN005 pin 3 (with external trigger to pin 1.

If you have any specific questions it may be best to contact me through betaheaven.com

regards Noel

Hi every body,

There is any body that has a SL-F45E servis manual or a some technical information.

I have a problem with this model and it's impossible to find any technical information.

With the technical diagram or schematics will be ok.

Thanks in advance

Does anyone have a front cover laying around for the Sanyo M10? Mine is missing the cover for the date/time/traking buttons.

Thanks for the advice Kev. Yes - I may love the picture quality of the Sonys but the Sanyos are easier to work on!

Based on other advice and research, the "dart-like" drop-outs are possibly due to the lack of drop-out compensator circuitry in this rather odd superbeta player-only. I have to also consider the possibility of residue still on one-or-more of the video heads as a tape was still wrapped around the heads when I opened it up. Some of the tape was "stuck" to the drum after 25 years of imprisonment.

I did recall your earlier posts with interference from other units and particularly some TVs (ie. plasmas) which seem to add "static-like dropouts". If I suspect this, I usually link up to my old Sony broadcast monitor and/or computer-transfer system. In all cases, the dart-like dropouts remain in this case so have sort-of ruled that out.

As I need to solve the capstan issue now, I am starting to suspect the capstan assy. On tape load, I can see the capstan do the same sort of "rock left, rock right" as a Sony head-drum with the hall-sensor failure so I need to look at that. Fivos also recommended to look at the SMD caps on the capstan assy board. There was some corrosion on this board so it is quite possible as the suspect. The fact the capstan speed was fine for about 1 day. Then the next day got faster and faster as the day progressed, then on the 3rd day wouldn't spin suspects a "dying" component - possibly that SMD cap.

I too have seen the "capstan speed up issue" on an HF100, but it wasn't actually my machine, so never needed to solve it. (Fingers crossed), my 3 working HF100s haven't had this issue.

Will update here with progress.

Hi, I recently acquired a Sony AG-90 Betamax Cassette Auto Changer that I would like to sell to anyone interested? It's in excellent condition and has been in storage for a while. I believe these are quite rare!

Rob:

I'm glad those Sony's are keeping you 'busy'. They can be a right pain as we both now.

Reading your comments about the dart like drop out's,there's a thing I would like to point out regarding what 'could' be responsible.

Do you remember when you had the other VTC 5000 and you sent me the video regarding the poor playback?. When I received it back it played perfectly for me.

There has also been two other occasions regarding a VTC NX100 and VTC M40 from two different individuals who purchased or had them overhauled by myself. As did you.

It turned out in the case of the M40 they guy had a VHS vcr on the top that caused his black drop out interference until he moved it off the M40.

The NX100 the guy found out he too had white dash like interference and brought it back only to find here it worked flawlessly. He found out a BLU Ray player he stacked on the top caused his issues.

Whether this is down to that and using todays screens (LED,LCD or plasma's) I don't know as I have a Sony C9 and Sanyo VHR874e stacked with no issues, but the lesson here appears to be if it's a beta VCR don't put other equipment on the top of it.

That could be your issue, with that anyways.

As for the speed issue I have an HF100 here with exactly the same problem. I've checked all components on the servo board. Tried the torque adjusting.

Replaced the entire servo board AND reel drive/spool board (with no issues) and it still continues to either go too slow, until you adjust the torque then when ejecting a tape it either won't play at all (until you speed up the torque) and then after a while it goes way too fast and cut's out the play mode. Other then that I have it A1 and seems to have been lightly used. The only other area I can think of is a varying power output from the PSU .All caps have been checked too. I also have replaced the torque potentiometer in case that had high resistance.

If you do find out what caused yours to do this I would love to hear about that.

Good luck....................Kev

Hi all - hope everyone is keeping well.

Thought I might ask a question about a rarely-spotted machine. The Sony SL-P8800R (PAL).

I went down to Wiltshire,UK this week to pick up some beta tapes and the sale included this player which the seller's son was given when he worked at Sony in the late 80s. I had never heard of the player which is stated as a "Super Beta Player".

You should be able to see my pics at https://drive.google.com/open?id=1uGKMf1IG7ax8mTe7enj4GqRHRFVz1hLT

As you can see:

1) It is a PLAYER (not a recorder).

2) It operates on European (220v) and US (110v) voltage

3) It's mono !

4) Has the main circuitry simplifed into a single board (SV-25).

I fixed many of the obvious problems (which included something nibbled through part of the external mains cable which had blown the internal 1.6A fuse. It needed a thorough clean and a tape had been left inside laced up for 25 years which had to be (gently) peeled away from the head drum. I also needed to strip down the tape spools, clean and re-oil.

I would welcome any knowledge the team have on this model - it must be pretty rare. I can only find one reference to it on google.

I would love to get this baby working but have an issue that maybe - in the absence of any known service manual - the community can help with ideas.

Problem 1) When I first powered it up after fixing the mains issue and cleaning, the machine played with many "dart-like" dropouts. I suspect this was residue on the heads from my imprisoned tape? Do you agree? What is the best approach here - I read that contact-cleaner on a swap followed by IPA to "wash off" the contact cleaner - but what do you guys think? There is not drop-out compensator circuitry on this machine BTW.

Problem 2) - The priority - Today when I powered up, a new problem appeared. At first the capstan started turning too fast. It got faster and faster until now - when you attempt to load a tape, the capstan nudges one-way, then back the other then stops. This causes the lace to abort and the tape is ejected.

In the absence of a service manual, I adjusted the "capstan freespeed" pot which did make an effect but was running too fast to use this to correct.

I also checked the capacitors in this area of the board. All okay.

I did notice some oxidisation around the IC on the capstan motor assembly which made me think about this area. I assume this type of capstan has a hall-sensor? Would you suspect this given the gradual speeding up then the observation of the capstan moving slightly one-way then another on "PLAY" then stopping? We talk about the hall-sensor on the head-drum, but never on the capstan assy.

Thoughts?

Hi everyone

I bought a Betamax at an estate sale about 2 years ago.

Well, finances got tuff finally and I want to sell it. Last night I went searching for

answers on my machine. Couldn't find it. So, I typed in the numbers of my machine FCC

and low and behold it comes back could not find. I contacted Fcc and they said I can sell it

so Here are the numbers on the back of the machine. It is UHF and VHS the silver nobs are side by side not up and down. and there are numbers etched into. Looks like its never been used. The numbers on this on the back are as fol

lows FCC AEZ9YB VCR 50/50

SILVER SANYO

AND HAS A WEIRD LOOKING SPIDER NEXT TO IT

SO ANY INTERESTED BUYERS CAN CONTACT ME FOR PICTURES AND MORE INFORMATION

THIS EMAIL IS GOING OUT TO DIFFERENT PLACES AS OF TODAY.

GOES TO THE HIGHEST BIDDER

Hi everyone.

I know this is the wrong board to post this but seeing as the v2000 chat page is not very well frequented I'd thought I'd ask here.

I'm in desperate need of a NOS pinch roller for a Pye 20vr23 (Philips vr2023 ) v2000 vcr please. The original on mine is totally hard with a shine over the surface. Even my trusty Rubber Renue can't save it and it's causing problems with the DTF and picture search modes.

Thanks again and sorry to post v2000 on here.

Regards

Rich.

Hello, Kev.

Not sure if e-mails reaching you on your .net account. Having problems with the NX100, although the 5150 to which you fitted replacement display and video heads is still working fantastically well...no surprises there!

Any chance you could e-mail me back when you have time?

Best wishes.

Phil
