I have my Loudenboomer running, but the efficiency is not what I think it should be, getting about 50% max, at about 800W in, CW.
Does anyone have measurements of theirs?
The PS was a mess, with terminal strip cut out, but simple to fix.
Amp seems bulletproof and well made.
The B+ wants to run very high. 90V gives me 3KV at idle, even with the bleeder changed to 50K!
The cap is 3KV, so I don’t dare run w/o the Variac!
Next will be to try class C, with an appropriate grid leak.
