Thanks Jeff.
Turned out that it did have Silver Mica disease after all, in the discriminator transformer. I performed the operation on it, removed the bad cap(s) on the bottom and soldered replacements below the chassis after reinstallation, and that seems to have cured it. Probably why the adjustment had been off to begin with - someone else had toyed with it before I got it.
I tweaked the adjustment as well as I could by ear, but I don't have access to an O-scope or sweep generator, nor does my friend that used to do TV repair long ago. The sound and tuning still seem just a touch "off" - problems narrowing in on some stations - the spectrum is so dense here the stations are practically on top of each other - so I broke down and gave it to a local repair guy to do a proper alignment - cost me more then the things probably worth, but I didn't get it to flip it.
I'm jealous of the stuff you guys back east have available - I'm in San Diego, and around here you can't find squat, not even for an exorbitant price in antique stores (though I've seen them sell knockoffs as "antique"). The thrift stores have pretty much nothing but black plastic '90's crap. The guy who's doing my radio alignment does have some cool antique radios, I think he's the only game in town though. I'd love to have a vintage TV, but have no idea where I'd ever find one here.
