The audio is very strong depending on the station setting, almost no audio buzz. Focus control just needed cleaning, works fine now. The hum bars were from not having the HV oscillator cover on.
I did a little experimenting with the HV oscillator feedback loop that goes over the 1B3 rectifier. I could set it at just about any position and the screen still lit up brightly.
