Andy, The potentiometer sits at the underside of the top part when in service position. It is motordriven through a belt and a gearbox which also pulls the screen for the volume readout using a dial string. Quite an arrangement. With all due respect Andy, and don't get me wrong, if you can't locate the potentiometer, this may not be a task for

Common fault. The belt may be worn but in most cases a gentle lubrication of the volume potentiometer will work wonders. I generally advice against the use of contact cleaner unless there's a chance to clean it off afterwards but in this case, where it's hard to get inside the potentiometer and sewing machine oil can't be found as an aerosole

Lovely machine ! I am not very familiar with the open reel decks but this guy knows what there is to know about these little gems and more : http://www.makarateyp.com/RZBO.htm Roland is a fellow collector and a good personal friend of mine. He reads english but may prefer to write in german. Martin

It will probably need cleaning and lubricating of the whole mechanism, motor etc. It's belt driven, one belt (in stock if you need). Martin

Yes, they are still available. You have an answer to your PM ! Martin

You are right about the counting though I am not quite sure when it counts or if it just checks for pulses. At the end of the record, when in the lead-out groove, the CPU merely detects that the pulses are coming in fast. The SO switch, I think, is there only to tell the home position (See EDIT below). At start the carriage is moved inwards until a

Probably in need of lubrication. The threaded carriage shaft will need cleaning and a couple of drops of acid-free oil (sewing-machine oil). Could also be the servo motor belt slipping. Martin

Yes, it looks like the one used in the good old 14-bit Beogram CD X (where it practically never fails, check those caps !). It will definitely NOT fit in any newer players. Martin

You are absolutely right about the output DIN connector (and muting) board. Check those wires before you close the Beogram after every service. I never had to flip an 8000 upside down to do any service. Leave the bottom plate on the table as you would normally do. Open the deck into service position. The manual says that the aluminum cover (over the

I couldn't agree more ! Servicing any tangential Beogram is not something you just do. I feel an urge to comment on the notes above: 1) The back hinge and dust cover is a really big liability in the 8000 series. The plastic is very vulnerable to cracking and really really challenging to put back in place. There's no need to take the back hinge
