I replaced all the paper caps in stages, pausing for a power up periodically.
Here's the first semblance of an image after replacing those incorrect vertical resistors and a few vertical caps.
While doing so, I discovered a 22 Meg feedback resistor had drifted up to over 35M which cause the oscillator to run much slower than it should.
I think those 68K resistors mentioned above were an attempt to fix this issue.
A few more replaced caps in the sync and horizontal circuits resulted in a stable image
Replacing all the HV caps resulted in a brighter raster.
Finally, after replacing all the paper caps.
Next up, I'll do the electrolytics and selenium rectifiers.
