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)

Bill:

The large black can is the HOT. The two 807s are connected in parallel and amplify the sawtooth feeding the primary.

The schematic of that portion of the set is here:

I'm thinking that the seller made a mistake on the CRT number. I know Dumont used a 15DP4, maybe others can chime in to confirm?

The DuMont Service notes indicate the crt in the Club model is a 15AP4.
