audiolover718, I assume by daisy chained you mean the duplex receptacle device is used as a junction point to wire from one outlet to the next and so on. If that is the case I would advise you to hire an electrician to change out all the cheap re... 
Can't tell,if my house is properly grounded
GOOD NEWS!!!So I found a proper cheater plug and tried putting it on the tube amp only - buzz completely gone whether the phono pre was on or off. So it appears the amp was to blame and the phono preamp just amplified the problem. The cheater plu...

Can't tell,if my house is properly grounded
One more test.With only the preamp connected to the power amp, TT not connected to the inputs of the preamp, unplug the preamp from the AC power.  Turn on power amp and check for the buzz/hum.

Can I use this amp in my house?
sbank,What size of amp/s are you looking at? I should have mentioned in my last post, just because the manufacture installs a 20 amp IEC inlet on the back of his equipment doesn't mean he had to do it to meet bare minimum electrical industry stand... 
Can I use this amp in my house?
But I will add that I just got a Krell FPB-300, with a 20amp plug, and it came with a cord that has the 20amp connector for the amp on one end, and the other end has a standard 15 amp plug on it. Crazy ain’t it? And it might even be a Listed powe...

Hodu,At 200 watts per channel amp if you will be pushing the amp with high dynamic music don't let the electrician talk you into using #12awg wire. #12 is bare minimum for a 20 amp circuit. Stick to your guns and tell him #10 wire.You want the mai...
