The Falcons where built by Andy, as previously stated, and they are very similiar to the Loudmouth designs (do research and figure out why
).
Your amp will pull over 100 amps on a peak. I ran a Pal 350 MDX which was a 1 driving 3 8950 amp, and it would pull >100 amps regularly.
I wouldn't drive it with more than about 3 to 4 watts of carrier, and your tubes should last a good long time.
Power supply wise? A single 165 amp leece neville would be able to power that amp, as well as anything else you had hooked to it.
However, you might be just as well off selling that amp, not purchasing the monster electric system to power it with, and purchasing a solid state amp. Solid state amps don't have the inefficient switching power supply that costs you amperage just to run.
However, that ZZZZZZXZZZZZZZ sound in the background is unmistakable. 15 yrs ago that WAS the sound of a mobile big-strapper!
