Some quick pics. The horizontal AFC subchassis stands above the main chassis:
The not-well-shielded tuner is at lower right in this view:
Underneath, I see a handful of replaced caps. The original small caps are the flat molded-paper type. At lower left, someone replaced a resistor between the horizontal sync and horizontal centering controls with a pair of resistors that look burned. At lower right is the HV doubler. Everything on the doubler board (resistor chains, etc.) has been painted with black insulation that looks original.
The tuner uses ganged air variable capacitors (!), similar to the General Instruments tuner in the unknown TV in my Scott 800B combo. Pilot TV-37s use a simpler tuner of that sort.
Uh-oh. One of the CRT leads snapped right at glass level.
Maybe I can grind away enough glass to solder on a new lead.
Time to gather up replacement parts. The missing tubes are common types. I should have most of them on hand.
