Back on this one. Found a problem! The 3.3KOhm 1 watt resistor off pin 1 of the 12AU7 video amp that I replaced overheated and was open! Heady in my discovery, I soldered a 2 watt in place, and put the set back together.
Powered it up, and the horizontal output tube lit up like a Christmas tree. And then the smoke started coming from underneath the HV cage. Powered it down as quick as I could.
Dammit
