Powered up with isolation xfmr and variac. No load, no tubes - just transformer voltages.
I don't care about the values - they simply should make sense.
All seem to be good so far - all filament voltages are present, the voltage between the rectifier's anodes is good and rises fast when you turn the variac.
OK, now after I confirm there is no shorts to the DC load I have to bring the speaker.
God help me!
