Hi All;
Ron, it can pass RF from my Signal Generator, but not from the Antenna, its as though the input from the Antenna is too weak.. I can tune it to various places on the Dial, and re-tune my Signal Generator to that place and it picks that up fine.. I have wired arround the Wave Trap as that is open, and since the Signal Generator Signal is getting thru, I am not sure what to look at or for next..
All Paper Caps have been replaced, as have all out of tolerance Resistors, all but one Mica Caps have been replaced and the one that hasn't been replaced is C-5..
