Philco 43 - Filter Choke
#1

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
