38-116 needs Dr. Philco.Resolved.
#11

(01-21-2016, 02:18 PM)AI2V Wrote:  The first voltage I would have measured is pin 5 of the 6L6; that's typically around -15 volts.  

I would suspect that you have a problem in the resistor network that's connected to the B+ center tap winding.  If the pin 5 voltage is wacky, go to those resistors; one of them has gone way high in value.
Did that and they check -20v on both tubes.
I am satisfied now that it has about as good a sound as it gets.
Plenty of volume as well.
Back in the cabinet now and on to the next one.
Thanks for all the help everyone.
