if i read parts 1 and 2 of the links correctly it has its preamp and driver = still massive
from the end of part 2:
She has been on (off at night whilst I am in bed) and like this for about ten days on soak-test now, and believe me…the blue plasma glow in the 807’s (which they are quite famous for doing) is getting better and better by the day! My next move is the pre-amp and drive stages.
He has circuit provisions for a 6SN7-based preamp with EL36's for drivers, but they're not installed yet. All he's posted so far is power supply and output stage test measurements, which BTW, are incredibly impressive. A pair of EL36's, not-so-coincidentally, make around 60 watts when run in pairs.
