Sort of, but only in the distortion business (guitar amp). And not much
there (at least until I can find a chassis for the amp).

And a power supply capable of delivering 1000W for the heaters alone
(assuming your tubes' heaters are similar to 12ax7's). For 12ax7's, that
would be 0.15A*500 = 75A. AC is probably good enough (if you can bias the
grids positive enough from cathode to get rid of hum) so you'll only need
a transformer & wiring to handle that, not regulator.

Yea. Four hours of Acoustics 2 does that for me... (it's supposed to be
acoustics. Thus far we've examined mostly mass-spring systems etc...)
Which is the reason I'm replying to this ;)
