Welp, the set's got audio, and makes a raster. Sort of
No vertical deflection, but everything else is where it should be. I tested resistances of everything in the HV/horizontal before power up and everything is where it should be. Now, on to the vertical.
Centering control moves the line about an inch.
In retrospect, the ONLY thing I can think of was that resistor simply arcing to chassis. Might not have been enough clearance there.
