Admiral 20X1 No HV

This is a update of what is a very old thread. I have No HV. The Horiz osc coil was bad and has been replaced. I have my osc back again, but No HV. All caps have been replaced and some even subed again. Resistors replaced as needed and HOT and damper sub'd. I have 100 v pp drive to the HOT grid and cathode voltage about 2.8 volts. I can tease some slight HV RF off the plate of the HOT and HV rect. with an insulated tool. The HV trans checks reasonably close resistance wise. I believe if there were shorted turns there would be excessive current draw (or smoke). Yoke resistance seems close also.
This was working and stopped (due to the osc coil) and the osc coil was replaced. Wiring has been checked, checked and rechecked along with component values. I am overlooking something and hope there is an educated bit of experience out there that can be of help. I was in the biz for a number of years and Im a bit supprised this is eatin my lunch!
