Hi Terry,
I was working on this radio over the weekend. I had the load buzz before I changed the speaker wires but not now.
While it was on resistor #22 on Philco 60 schematic a 10,000 ohms was running hot and metered out at 14,000 so I replaced it with a 10K resistor. The 10K resistor cooked immediately. What do you think cased the problem? Also on tube 42 sometimes I will get over 900V other times it will be in a normal range. Does that make any sense to you?
Thanks, Ralph
