49-501 question
#1

Hey, Philcophiles!
I have a question for our resident Philco gurus. I'm going through a 49-501 "boomerang" right now.
In going over the schematic, I notice that C303, a "special" capacitor, .2 mf at 400v, the cap that goes from the B- to chassis ground, is shown with an inductor in series with this capacitor.
Does that cap REALLY have an
And how should I go about replacing this "special condenser"?

I am almost done with that MONSTER 16B. What an excersize in tediousness! All of a sudden, I have no OUTPUT!
In troubleshooting, I found the output trans and the feild coil/input choke is shorted together!! All four connections !
I'm hoping I can remove the speaker and spread these wires apart to take care of the short. Anyone else ever run into this?
