Hi All

I am having a hard time getting a Philco 96 working correctly.
The radio section works perfectly, however there is distortion in the audio.
With a signal tracer the audio is clean and undistorted up to the grid of the first audio tube (27) but
on the plate it’s distorting. The info I have states there should be 27 volts on the plate, however I have about 
110-120 volts. I find that this voltage varies by going up from about 60v off station but once tuned into a station the voltage goes up ??
The grid voltage also goes up from say -3v to -16-18v.
Can anyone help me on this ?
Thanks in advance
Roy
