Update...
Talked w/ Dale on the phone to find that he have a bad connection in the filament circuit. With the filaments not conducting there is no load on the HV supply that's why the HV was too high.
After cleaning up the tube sockets it was sort of working. It also had a very leaky .004 coupling cap at the audio output tube's control grid. After replacement it working much better.

Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
