Just curious-- what is that large-ish black can with leads connecting to the top caps of those two power tubes? Bill(oc)

That's a couple of 807 tubes. Horizontal Deflection Circuit.

Thought they looked like 807s with that butterscotch colored base. Never seen 807s used in TV service before. So the HV rect is under the chassis?

The High Voltage rectifier and low voltage power supplies are on a separate chassis.

So.. The HV supply is RF ('non-flyback') type, and the CRT is electromagnetic deflection. Fascinating (Mr.Spock). Could you elaborate a bit more on the H deflection system using those two 807s? That large black can is a transformer(?). Thanks. Bill(oc)
