I would recommend pulling the HOT and doing a slow startup with a variac, a metered one is best (amps and volts), start out at about 10vac and see what the current is (should be nil), ramp up slowly over time, checking the filter can for heat, monitor the B+ (there is a tp on the chroma board, should be marked with 390 or 410v iirc). I stop when I can get it to about 400v which is around 80vac. If all that goes well then pop in the HOT with a cathode break to check the current. Do a full power start, and keep an eye on the HOT current, if it goes over 220, just pull the plug. Start trouble shooting.
the Vert circuit is kinda fussy, the .0082 cap off the plate of the 6GF7 takes a real beating, so if you have issues with the vert check that one and the 50uf cap electro on the same board.
