Hello -

I purchased a Beomaster 5500 and some related pieces last year from the original owner.  All of them were in pristine condition, and they sound great (over a pair of RL 140's).  Within the past few weeks the receiver has started to transmit a high-pitched noise whenever I adjust the volume.  The sound comes from both speakers, and lasts only so long as the red volume-level lights on the receiver are on.  Given its transient nature, I can live with the problem.  I'm curious, though, as to whether anyone has an idea what the cause may be.  Is it possible that it's the beginning of a bigger problem (i.e., a continuous high-pitched sound)?

 Thanks for any input.

Sounds like a capacitor problem. In this case, I would concentrate on the smaller caps in the power supply area and the caps on the processor module. It's the control signals from the processor that goes through to the signal path.
