You might try a 12AX7 or 12AT7, 12AY7, etc. just for testing purposes, I think they all have pretty much the same pinout as the 12AZ7...

If a 12AU7 will work, then I'm set. Back at it this evening

Getting better, now I think it's probably a matter of adjustment or calibration somehow.....

Decided to set the tester aside, and rip the VCR with on-screen menus out of the living room.

Seems that I only made things a bit worse, which is no big deal, but I notied that 2 or 3 of the controls (one was for blue convergence, where I have a problem) have absolutely no effect when turned. Is it possible that I have a bad convergence board?

I would check the caps/resistors on the board. Should be pretty easy since you can pull the board and set it on top or maybe on a chair near the rear of the set. Also, try spraying some cleaner in the controls.
