Well, I did some more poking around. I replaced a small electrolytic in the vertical section, just because I knew it was going to be replaced eventually, and I had one on hand.
I did some more checking in the HV section. There are two 1.5 meg 1 W resistors that the Sam's indicates should be a matched pair. Both read a bit high, so I replaced them with new metal film 1 W resistors (2% tolerance). I checked a couple other parts, and tested a big 7W 13K resistor. It read... uh.. I do have these leads connected... wiggle. wiggle. poke.... it's open.
So, another drive to my friendly neighborhood electronics store, and $5 later, I had a brand new, old stock, 13K 8W non-inductive resistor. I installed it, put the set back together, and... it's alive! I did some quick tweaking and hooked up the cable. It took me a while to get a good color picture from the cable - I think the tuner might be a little out of alignment. I hooked up a DVD player with an RF modulator and was able to get a pretty decent color picture. It doesn't fill the entire screen - the bottom inch or so isn't used. Convergence could be better. It's not terribly rich or bright, I had to turn the color and tint pretty much all the way up to get normal color. There are some retrace lines at the top - probably macrovision from the DVD though. And I'm sure it would look a lot better if I wasn't next to a window.
But... it's alive.
