Hello,

This is my first post here. My neighbor gave me a nice beomaster 6000 4ch type 2702 tuner amplifier.

I have a problem with one of the electromagnetic clutches. actually the coil part is ok but there is a white sliding part (looks like nylon) that moves with the metal pulley that's attracted when the coil of the clutch is powered. The sliding part seems to have too much friction. It doesn't completely disengaged when you stop pressing a button. If I press another set of +/- buttons then also the other one moves. I would like to know with what kind of grease i could make it slide smoothly again or is there another solution?

I shortened the drive belts and that seems to work but they won't last long i guess.  Is there a source for these drive belts?

I also need a few light bulbs for volume/tone balance display They are 12V 30mA

Any help would be welcome.

Best regards,

Ron.
