Thanks, Bob. That schematic looks like the Philco schematic that I got from Cliff, with the addition of a bunch of test points (A, B, etc.). If those refer to scope waveforms, they would be good to have, but let me digest this material for a couple of days before you spend a lot of time scanning. I am already struggling to retain my sanity with two sets of docs (Sams & Philco) both marked up and cross-referenced with part numbers from the other set. If I add a third set and try to cross-reference those printouts to the others, the world might explode.
I keep thinking that I'm only about half an hour away from whipping this mutt into watchable condition, but that's probably a fantasy. I should just slow down and try to learn something
My tuner plate looks like the one pictured -- an eight-position tuner including Channel 1.
