Made it about 3/4 of the way through the resistors....so far so good. Board grounds are fine.

Part of what makes this repair difficult for me is that I have to set aside a lot of the methodology I use to fix early b/w sets. It's been my experience with color sets that trying to component test at random just doesn't work the way it does with early black and white, which is what I'm used to.

For example, if you have a vertical sync problem with an early b/w, just start testing and replacing resistors in that whole section, because chances are that even if none are wildly off, most of them will *be* off by enough that it will destabilize the whole circuit. So far I haven't found a single resistor that's made it out of its 10% tolerance.
