I have changed the 4 meg resistor to 2 meg as on philco repair bench it play louder but still has the distortion and hum tried unhooking the winding used as the grid cap replaced it with 120 pf cap but still has the distortion and hum tried a 56 pf cap with no change. I read that a smaller grid cap would reduce distortion but it did not for me.

Any more ideas
