The three Beogram 8000 units are in various states of disassembly. My goal is to get at least one functioning and ideally, all three.  However one of the turntables came with broken tonearm wires.  I used that tonearm to learn how to remove the cartridge mount in my Beogram 400x thread (using Martin's boiling water technique).  Since that repair will be the most difficult it moves it to the end of the line.  I will pick one of the candidates that has the most chance of success to be first. 

Here are some of the parts removed from the three Beograms.  All three also have bad tacho discs.  I have one of Martin's metal tacho disc replacements so I will order additional discs if the chance of repairing more than one turntable is possible.

Here is one of the Beogram tach discs that is actually in decent shape. It is starting to peel though so it needs a metal disc replacement.

This Beogram 8000 tacho disc is really shot.

I noticed that two of my Beogram 8000 turntables are fairly close in serial numbers and have the same kind of tach sensor.

The third Beogram 8000 is a later serial number and has a slightly different tach sensor assembly.

My next step is to decide which of the turntables with good tonearm assemblies I'll start with and I need to go through the circuit boards to see if I have all of the replacement capacitors in stock. Hopefully I can start working on the first Beogram this week.

I'm looking forward to this thread, I can't get enough of the 8000 series 👍

while your in there check the condition of the 3 optos , 1 under the tone arm and the 2 inside the keypad, one of my machines the silver coating had faded so measured working but were no longer doing thier job well enough and adjustments couldn't compensate .

replacing all 3 worked wonders.

You are referring to the photo resistors 5R1 (for the tonearm) and R9, R10 (for the keypad)?  Where did you get your replacements?

Yes the photo risistors, the ones I used were just what I had in stock at the time, smaller than the original but worked perfectly.

bought from cpc , code re04698
