From the Bugera BTX36000 User Manual:
Output power
Peak power, both channels driven__2 x 1950 W / 2 Ω
Peak power, both channels driven__2 x 1380 W / 4 Ω
Peak power, both channels driven__2 x 800 W / 8 Ω
Peak power, bridged mono___________3800 W / 4 Ω
EDIT: RMS = Peak/2
peak power... heh...
just FWIW---- there is NO WAY to produce 3600 watts of output from *anything* plugged into a 15 amp outlet. not even for a millisecond (peak power). unless we are talking about a step-up transformer or something (not an instrument amplifier), and even then i am not sure how that would add up.
15A * 120 VAC = 1800 watts (from the wall). and while i am neither a scientist or an electrician, i am 99.99% certain that "continuous" draw needs to be at 80% or less of the circuit's maximum rating to be safe and reliable. wonder what the bugera says right next to the power plug socket?
The Bugera's are Berhinger's new pro line. Most impressive are the instructions as they come in about 40 languages and the English one actually reads like an English PhD technical writer wrote it!
My son, who is an English PhD with a MA in Technical Writing, agrees (he's guitarist too)

3600 watts? isn't that the point where two Acme 4x10s really start to open up?
You are right. The maximum power you can draw from a 120 VAC socket giving 15A is 1800 watts. No step-up transformer will increase said power, as increasing the voltage leads to a proportional decrease in current, even if using a 100% efficient power transformer.
There are some ways to get around this. Since amplifiers do not put out their max power all the time, using large capacitors on DC to store power will allow the amp to temporarily go over the 1800W limit. Tube amps do this, if i am not wrong.
However, even if your amplifier ran at a full 1800 watts, that's still only the INPUT power. Few amplifiers are near 100% efficient, as you can tell from the heat they produce.
Alternatively most of the rest of the civilised world runs on 240 VAC, giving a total 3600W input power on 15A.
Wait - isn't this the thing that powered Marty's Delorean in Back to the Future?
I have a Bugera 333XL all tube guitar amp. Its a Marshall at 1/4 the cost (I have the same head in a Marshall so its been compared A to B).
