PostSubject: newbie request for help   November 30th 2012, 11:23 am

I recently did a partial recap of a Philco E-814, only to find that it also had SMD. I replaced the wafer caps in the IF cans with 100pF silver mica caps, and now the radio only picks up one station (1630 kHz/10,000 watts/5 miles away). The station shows up on multiple points on the dial with silence in between. It's almost as if the variable capacitor has no effect at all. I'm not sure of where I went wrong--I'm just sure that I've gone way wrong somewhere.

Any help or advice would be greatly appreciated.

Its hard to guess, but you may have a disconnected wire or a bad tube, as only the strong signals a leaking through. A bad bypass resistor or cap in one of the grid circuits? Try signal tracing if you have a tracer.
