I'll cut and paste it when I get home (on phone now)
Basically, he said pull 1st 12AX7. If hum goes away its probably that tube. If its still there its a bad filter cap or another tube down the line or mismatched output tubes. I did pull the tube. Hum was gone but I had a quiet static (probably louder than the original hum but still very low. I sent him what I found and he said it probably the tube. If not its a ground loop issue. I'm reasonably confident if not word for word what he sent me. I'll double check and correct it if I'm wrong
