The filter choke in the radio is shot. The original choke had an inductance of 100H and a resistance of 2100 ohms. I ordered a replacement choke from Radio Daze part 154E which is 20H at 1666 ohms
First question - looking at the Philco Book - Condensers and More it tells me if I replace the filter choke with an lower inductance I need to increase the associated filter capacitor. Based the attached schematic I think this would be item 47. But how much should I increase the Electrolytic condenser right now i have a 1 8mf.
Second question - I read another post where it said you could replace the choke with a two watt 2100 ohm resistor and also increase the mf's of the condenser. So if i used this method again would this be item 47 and what mf should I use
