I got to the point where all my "fixing" was just introducing new errors, so I walked away from the project for a few days. In fact, I was going to drop this project and move on to something else, but, "As soon as I think I'm out, it pulls me back in." I can always find one more thing to try.
Yes, (Phil) I did try replacing those mica caps. Due to an unfortunate lapse of attention, I forgot they were 1KV caps and I replaced them with 630V caps. That's how I burned up the horizontal size pot. I have since replaced both the caps and the pot.
Then I made one last change in the wiring. My set, Phil's recently restored 19A1, and the Sams 19A1 photo all show this connection to the horizontal size pot, so I left it like that even though it didn't agree with my 17T1 schematic.
That's how it is in the Sams schematic, but the Wallace and Riders schematics are different, so I rewired it according to the Wallace 17T1 schematic.
The outcome didn't change much even though I imagine I can see a better image. It still comes up short on horizontal size.
I think I'm done replacing caps and resistors and I've rewired to entirely conform with the schematic. Now I have to ask about the significance of these voltage readings (actual voltage in red). My last bit of rewiring from the sync amp plate (pin 2) reduced the voltage from 125V to 77V. I have no idea if the voltage variance from the HV rectifier (corona ring) to pin 5 on the HV oscillator means anything at all.
Anyone have a clue what could be doing bad things to the horizontal hold and horizontal size? Here's a link to the full schematic:

Is it time to put this set back on the shelf? Thanks for your attention.
