I just did some more testing and here are the answers to some of the
questions raised yesterday.
Measuring the B+ All tubes removed
Voltage measured at the + side of C39 = 700vdc
Voltage measured at the + side of C40 = 348vdc
With radio unplugged and power supply isolated from rest of radio:
Resistance on lead going to the 6146 (V3) Final Amp - 32 ohms
Resistance on lead going to remaining sections - infinity
C19 is not shorted
Would it be advisable to start re-inserting tubes one at a time and see how
that works? Maybe that would more definitively isolate the problem. Good
idea or not?
