Jea 48,
Just last night I did another experiment- connected both power amps and preamp to a single outlet with a power strip, no cheater plugs- faint hum in the R channel and louder hum in the left.
Funny thing is, that I have the same model power amp before, just in stereo configuration (BAT-75 SE), and had the SAME problem, hum louder in the L channel.
I am absolutely sure the amps are fine, they are on loan from my friend, and are absolutely quiet in his system.
I didn't take them to my living room system to try, just because they are so heavy.
I will try again with no ICs connected, but then I'd have to use plugs in the inputs, otherwise they pick- up noise as antennas.
Ghstudio,
I'm pretty sure my electrical is up to code, as Jea48 seems to agree with.
