I received the Heathkit rf generator, it seems to work well. I'm assuming it needs to be recapped, at least the electrolytics, but I took my chances.
I performed what I think is a solid alignment on the radio, the dial is almost perfect now and the IF was very carefully peaked. I used the audio out instead of the AVC this time, just in case it changes anything, based on the instructions on the schematic. Still won't oscillate on the bottom 2/3rds. But the audio is significantly better, and I was immediately able to hear 1510 WLAC loud and clear from Nashville. Steps in the right direction.
I've exhausted my options, time to rewind the coil again.
Greg, how is yours going?
