Philco 80 Alignment
#3

Quote:I think first you shoud turn the regen trimmer out so the radio is far from going to squeeling mode. This will likely take care of the howling and the birdies.

I have backed off the regen trimmer almost to the point of no compression and everywhere in between. When I tune a station and make an adjustment to the regen trimmer the station then comes in clear. But just the slightest movement of the dial either way and it squeals and howls loudly. Slightest as is the width of a dial line. Further adjustment at that point does not help.

I went back through the procedure several times thinking that it is just so far out that I need to bring it back in slowly. Same order, over and over.

Is it possible that the oscillator coil is or maybe bad and thus I'm aligning everything wrong? I did not pull the coil in this set during the re-cap. Or maybe the regen cap?
