Car Radio Problem
#1

Hi Gang,
I just finished working on a Philco Model 5 Packard car radio. That set was quite a piece of engineering and a dream to work on. So now I am now working on this 1956 Chevy manual-tune radio model 987366. I re-capped it and B+ voltages were right on. It was playing away on the bench when suddenly I heard the vibrator frequency drop and the current started to spike. I cut the power and started checking things out. Everything seemed fine so I pulled the vibrator/rectifier and supplied 245V directly to pin 8 of OZ4 socket with my bench power supply. The radio plays great. Current draw is about 40mA but I don't have any idea what it should be. Does that sound reasonable?

Thanks,
Ron
