Philco 46-1209 Code 121
#15

Bob,

I have not aligned the set at this point as I did not think that was necessary until the rest of the 'problem' areas had been taken care of. Please correct me if this is wrong. It would also be my first alignment, and I am not to confident of the signal generator that I have.

Chris,

As I understand what you are saying is that there are 2 problems going on. One with the 7X7 tube and one with the 6V6 grid. I think I understand the schematic to show the pin 3 connections on the 7X7 tube to lead to the volume control and to a connection leading to pin 5 of both 6V6's. It also leads back to the (-) side of the 20 mfd electrolytic which has the 135 ohm 10 watt candohm resistor leading to the chassis ground. The center tap also leads to the (-) side of this electrolytic as well. Am I incorrect in assuming that this is the ground off set resistor that you are talking about? I have tried swapping the 7X7 tube with a XXFM tube that was known good and I had the same result of the plates cherrying.

Thanks for the help so far, it is very much appreciated.
