P.S. Also, I live in New York City and the power here is pretty bad. But most of my amps are quiet, especially my BHK 250. It’s actually one of the quietest. That’s why I suggested so many things unrelated to power issues.
Detecting “Dirty” Power
I bought a used BHK 250 still under warranty. It is plugged into a Denali S power conditioner. I heard a hum coming from the area around the tubes. I cannot hear it from my sitting position and it doesn’t effect SQ, but I want it gone.
I sent it to PS Audio; they tell me there is no hum and sent it back. They implied I mostly likely have a power problem and recommended some troubleshooting steps. I unplugged everything from the 250 and plugged it straight into the PS Audio receptacle. The hum is still there, but it is not as pronounced. A P15 power regenerator might fix the problem, but I want to know if I have a power problem before I do anything.
How can I determine the quality of the power coming into my house and out of the receptacle? FYI, the Denali is plugged into a PS Audio receptacle/dedicated 20 amp line. I have a whole house generator w/ transfer switch and whole house surge protector.
