So what I'm thinking is that the 6AU6 plate is being shorted to something and the screen is acting as the plate to get a signal for the audio. What voltage do you have on the plate and screen (pins 5 and 6)? How about the 6.8K, 4.7K resistors and 20uF cap?
Good luck!

Jesus...I have -0.5V on the plate and 180V on the screen. 180V through the whole circuit all the way to the 20uf electrolytic. I'm grounded to B-
