I pulled the 6CG7 multivibrator tube and connected the TV Analyst's grid drive to the HOT grid, and got a bright raster.

The Analyst makes a nice clean signal:



A label on the PC board points to the HOT grid:



The HV is back, yay!



The raster is nice and bright with full horizontal deflection. The vertical locks, but the maximum height is what you see in the photo.

Perhaps replacing the K7 couplate will fix the HV problem, after all. Not sure what to think about the height problem. When I played it before recapping, the height was lacking somewhat, but not as much as now. I would have expected recapping to improve the height, if anything. With my luck, the vertical integrator (K4 couplate -- ugh) is also flaky.
