Next, we need to power the filament of the 4-250a. While the 12AX7 and 7591 or EL34 will draw about 2 amps combined, the 4-250a's filament sucks a little over 14 amps at 5 volts! That's 70 freaking watts! I'd be happy to have just that in audio output! More than likely I'll buy a regulated switching supply for it.
