Well, I tried to give this a shot by myself. Without the output tubes installed (all others in place), I turned it on and measured some voltages. On pin #2 of the output tubes I had approx. -16 to -18 volts dc. Pin #6/9 had 350 volts dc. Pin #7 had 447 volts dc. Per the schematic, I adjusted each of the bias adjusters till there was -17 volts at pin #2 of the tubes. By then, I could already feel the two big "log" resistors getting HOT.
Installed the 4 output tubes and fired it back up...
The good news...sounds good!
The bad news...I rechecked the voltages and noted the voltages at pins 6/9 went up to 370volts dc. I checked the current draw of the tubes (across the cathode resistors I installed) and two were running 52ma (52mv), one at 39ma (39mv), and one at 36ma (36mv).
At this point I plugged in my ipod to the AUX input and tested that. Played a song for a couple minutes. No obvious sound issues, but oh yeah, those resistors are so hot I can't touch them!
So, what's my next step? Please help me out guys!!
