21-CT-55 power supply failure

[miniman82]

Now it's obvious that some circuit is taxing the power supply big time, even with the sweep tubes out the ballast is getting really hot and B+ is still 15 volts low. The drain appears to be on the 285 volt rail, so I guess I'm just gonna have to start disconnecting things till the load goes away. I think maybe a cap somewhere has (partially?) shorted or something.

Also tried replacing the seleniums with diodes, didn't change a thing.
