Hi,
I just finished re-capping the electrolytic and filter bank capacitors, and fired up the radio and was pleased to see a marked improvement (thanks for the assistance of my online mentor, John Goller!)
However, on the AM broadcast band, once I tune past 1050 kHz, I only get awful crackling. The problem seems to be with the rotor/stator plate spacing. I tweaked a couple, and the crackling changed to a consistent, well, sound like a fly passing gas, if a fly could do that.
I notice the plates are very close together. I can't seem to fix the problem.
I have two questions:
1) Are the rotor plates supposed to be centered with respect to the stator plates, or to one side, close to them?
2) If they are supposed to be centered, how can I do that?
Any and all suggestions are welcome!
