I can already tell that convergence is going to be a pain in the ass on this set, even though I'm going to have to pull all things off the CRT for safety's sake when I attempt the cataract repair, I have already tried convergence a few times to see how it's going to behave.
First off, I DO NOT like the convergence clover on this set, it sits way too loose on the neck, held in place by spring clamps, way too easy to shift it's position when you try to turn the static adjustment magnets,(discs) which are in an awkward position and hard to turn, I might try to lube them up a bit to make them glide a bit better.
The dynamic convergence is showing signs of trouble, this is not unexpected as I have not gone over the convergence PCB yet, I fully expect the diode array to be tired and out of spec, have already ordered a replacement NTE120, would not be surprised to find worn resistors, just know I'm seeing the same type of non linearity that can't quite be adjusted out that I have seen before when there are parts worn on the convergence PCB.
The old focus rectifier was replaced this weekend by 4 of the cheepy 20kv diodes, 2 in series , in parallel, seems to be holding up OK, and made a slight improvement in focus range.
