Trying to Restore 48-472 code 122
#15

Good news!! I replaced the multi-section filter cap with 3 Electrolytics, and the radio started playing.... No I have a couple new questions.

1.) when I turned the radio on previously in a few seconds I had a very loud hum, now when I turn it on its nice and silent, but I hear some hum when the AM radio is on. Where should I start with that?

2.) The FM does not work at all, when I turn the knob for FM the radio goes silent I can turn the volume and tone up all the way and its dead silent. The tubes seem to stay lit, but its dead silence...

3.) I only twisted the electrolytics together with the wires just to test it. Nothing is soldered in yet. The capacitors the guy at the store gave me were (2) 42 UF and 100UF the original one was 40, 70, and 40. He told me when he replaces filter caps on his old radios thats what he uses. Can the 100UF be the problem?

4.) How does the loop antenna get connected someone cut most of the wires off, but the loop still looks intact.
