FM works!
With some detailed directions from TV Engineer, I recapped all the IF transformers over a series of afternoons and evenings. That was some incredibly delicate work.
FM works now, although with hiss and sometimes distortion, indicating it needs to be aligned. Stations come in stronger on AFC than without.
I get a little mains hum on AM, and if I rotate the dial quick, I can get "thumps" that are probably stations, so AM probably works, but the alignment is WAY off. Although when I first brought the set up on the variac, there was a little bit of static followed by a small POP, so maybe something toasted. I pray it's not inside one of the cans (coil grounded to chassis). I can get some small pops when I touch a screwdriver to the AM antenna connection, so that's a hopeful...
