I made some progress on this. I did the usual recap, and had to replace a few caps and resistors that were taken off the horiz/vert board and never put back. And when I tried it I got ... nothing. But after poking around I found the trouble was the horiz osc tube socket. After resoldering it to the board, I got a good picture with both horiz and vert sync, and sound with lots of buzzing in it. But the picture only fills the middle of the screen because the HV is way low, around 7.5kV. Then, yesterday I turned it on and the filaments burned out in that same horiz osc tube. I didn't have one, so now I'm waiting on a 9AU7 to arrive in the mail.
And I found the small piece that broke off the back by digging around in the box it came in.
I also finally got around to putting together this little 8" RCA, that I had already basically finished fixing 2 years ago.
