I don't think your problem has anything to do with voltage. I believe your heat sinks are screwed to the chassis too tightly and so they are ringing (think tuning fork). This wouldn't be a Krell, would it? I know some Krells do that. The best way to stop it IMO is to BARELY loosen the heat sink mounting screws so the system becomes more mechanically lossy. Something like 1/8th turn or less. I helped an exasperated guy here on Agon solve this problem that way and the ringing never came back.
Input voltage and your poweramp
I have a pair of solid state mono block amps that's make excessive noise from their chassis. It's a loud buzz that develops to a rattle at times. Their tech is saying the problem is caused by the voltage level from, which fluctuates down to 116V. The utility company is telling me that the voltage is normal. For those here in the US, can you measure the voltage level at your socket? Thx.
