I have been reading over the schematics and I cant seem to figure this out.
Probably won't do much HV wise without the yoke hooked up (The sweep circuits go out of tune without the yoke, and RCA often put jumpers that complete the HV B+ wiring in the yoke plug to prevent sweep circuits from running without it connected). Reconnect the yoke, then if it still ain't producing HV make sure the bias voltages on the Horizontal output tube are correct.
