Apart from the dial cord seemingly be broken my recently acquired BM2000, when delivering nice sounds through my S-45's, turns out to get very hot (heatsinks). Is that normal/acceptable?
No!It needs repairs to the output amplifiers.Replace the idle current trimmers and readjust to factory specs.Do one channel at a time, begin with the channel with the currently highest idle current.Don't use it until repaired.

I will start the surgery shortly while taking a deep breath.
thanks and regards.
I happened to have a donor BM2000, of which I replaced the amp IC's long ago, whereas I activated this receiver only a couple of times.
Is it possible to swop the amplifier board with the heatsink attached as a whole with the unit from the problem BM.
Kind regards

That would be over-complicated!Just replace the trimmers and readjust them.The trimmers on the other board will most likely also need replacing - if not now then very soon.
After being half a year off "forum air" and away from BEO..'s I owe you a feedback on the above problem.
I followed Dillon's advice and replaced the trimmers, set at the same value as the malfunctioning ones: result : no heating anymore and a nice clean sound from the speakers.
Itis now time to turn to my Beocord 1200 and Beogram1800 ( ref my other threads)
Thanks a lot
