Default Pioneer CT-333 stereo cassette deck

Hi folks,
I picked up this deck as a non-worker at RetroTech today and it has a really weird problem where it will play snatches of the tape about every second and it appears to be a problem with the mechanism of the actual deck.
Rewind and fast forward don't work.

The amplifier works as I can hear snatches of the tapes being played.

Any idea where I can find a service manual for it.
I found a manual on the internet but its in French, German and Italian!

Any words of wisdom on the workings of the mechanism would be welcome.

Alf

From what you are describing I assume that you can see the spools rotating intermittently with fragments of sound when the tape is actually moving. This symptom together with FF and Rewind not working is most likely a sign that the belts (and rubber tyres if present) are dried out /slack / broken and need replacing. If the manual shows how to expose the mechanism then step one is to open it up and have a look. You can often find sets of replacement belts etc on the web and advice on which suppliers to avoid. My experience is with just one supplier and all was well.

A bad main capstan belt can produce all sorts of strange symptoms. Take the cover off and have a look.

If the belt on this 1988 deck has never been changed then it's extremely likely to have failed.

Hi Paul,
Thanks for the link to the manual.

In the past, I've have frequently had trouble accessing this website and nearly every time I want to log in, I have to create a new password. Now they don't even recognise the email address that I have been using for the last 10 years. Now they're saying that due to abuse of the free system, they aren't allowing new registrations so I am stuck.

If anyone can download this CT-333 manual for me, it would be much appreciated.

Best wishes,
Alf

I see what you mean. I can't access it either.

You should be able to change the capstan belt without documentation though.

Hi Paul,
Yes, I agree but I don't think that is the problem.
I would like have the opportunity to check other possible points of failure.

If you can, take the mechanism out and examine it on the bench under good lighting.

Clean the tape path, the drive surfaces, check the belt, clean any sensors (switches, hall effect sensors, optointerrupters,) and generally look for any broken or worn plastic.

In a great deal of cases, this will get things going.

If you can connect it to the PCB while it's out of the case, then all the better, as you should be able to see what's happening as it runs. Check that the tape is being transported as you would expect with no slack or deviation as it passes the heads, and no damage (particularly creasing). Check that the head is in intimate contact with the tape and is pushing the tape against the sprung pressure pad in the cassette such that the springy strip is deformed into a curve and not left ruler-straight.

You'll get there, I'm sure, manual or not.
