Yep! That's the set I picked up in Rochester.
Looks like I'm going to have to order up some new caps. In the meantime, I replaced the tired 5U4 and the dodgy vert tube, and that made for some definite improvement. The height and v-lin can now at least be adjusted to something reasonably close to correct without throwing the vert oscillator way out (it still needs recapping though). ...And the width/HV performance is much better now with the new B+ rectifier-- the picture didn't quite fill the entire width fully before, and it bloomed if you advanced the brightness very far, but now it fills the screen nicely and blooming is about nil.
One thing I have noticed, though, is that this set has about the most pronounced "turn-off spot" I've ever seen on any TV. When you switch the set off, you get a *bright*, tightly-focused pin-point of light that takes several seconds to even *start* to defocus or dim out, and takes perhaps 30 seconds to fully disappear. You can even see a visible "halo" around the spot that looks sort of like when you have the intensity control turned up too high on an oscilloscope. I don't see any actual phosphor burn-in, but this can't possibly be good for the CRT... Is there a typical cause/solution for this, say a bleeder resistor in the HV section?
