49-1401 no audio
#7

Terry, something is wrong that the supply voltage after the B+ dropping resistors is so high, but I don't think its the output transformer. Owner said he had speaker audio if he applied signal to the grid of the 35L6.

Even with 190V supply to the 6AQ6 plate, there appears to be no voltage drop across the 220K plate resistor? less than half a milliamp would give over a 100V drop. Something definitely wrong there.
