Hallicrafters S-120
#4

Doing this without notes!!! C31A,B,C 47uf at 220-250 volts, R21 33ohms to 50ohms. R14 470k change to one watt or use 2 one half watt 1megs this is something I do with every radio using a 35C5 or 50C5. Consider adding a 50ohm to the filament string something I do most of the time. C31D 22uf 50 volt to 250 volt most of the time use 250 just what I have on hand most of the time. 12BE6 try different ones will make a difference on Band 4 forget the tube tester on this one. Simple long wire ant. 10-15 feet.   David
