Source components (cd player, TT, tapedeck) and preamp will probably be 20-30w each. I would think with a preamp and 2 sources running, for taping would be nearly 100w right there. (approximately 0.2-0.3 amps drawn as I see on the belkin power center)
The Jolida 50-60wpc Tube amp draws 1.3-1.5 amps. 180w
So if I'm calculating this properly, 280w.
--------------------------------------
If I use different amplification...
With the pioneer SX-1280, idle is right around 0.6amps = 72w
Power consumption is listed as 430w(UL) 1100w max
If I ever use the PS Audio again. That might be more of an issue. Manufacturer recommended at the time a dedicated 20a breaker for it. 200wpc 8ohms/400wpc 4ohm/1000wpc 1ohm.

My usage is much lower then that, as it is rare for me to reach a speakers reference efficiency in db. The pioneer's meters barely move when I use it.
I will likely stick with the Jolida Tube amp, 3 source/preamp combo.
Worse case might be monoblock tube amps, equivalent or less wpc.
I'm certain that the spike is from the neighbors florescent light in his kitchen. The bad AC might be the cause of his, and my panel buzzing. So I'll get an email out to CMP, but I'll probably talk to the landlord on monday.
If your designing something, it sounds like and expensive venture?
Thank You
