Stewart Warner T-711 help

[Radiotronman]

I have a Stewart warner t-711 I’ve recapped and it had high voltage at first and then disappeared. It’s basically the same as a ge 801 set. I can’t find any obvious bad resistor or what’s causing it. The fly looked suspect and I installed a new stancor nos one, but nothing changed. The 6bg6 hv output tube looks purple (gassy?) no matter which one I swap in. What am I missing here?
