you could check the B+ and see if its in the 400v range, that would clear the power supply.

when you say you found the focus coil wired "wrong" how was that determined?

did it look orig to the set?

still not clear on why the reg would be pulling ANY current at 19kv if it is that is wrong, would point to a bias issue between the flyback and the B+.

you need to understand how it works, at 19kv the shunt tube should be fully biased off, if its not there is a problem. At some point. Since the boost voltage is used in the grid circuit of the shunt, I would look there. for some reason I think you have term 1 and 2 reversed on the fly. that or something with how the focus coil is connected.

oh and dont just swap the 1 and 2 to see if I am right, just triple check the schematic to see if you have it right.
