Philco 19 Code 128
#13

Question for anyone (reference tube socket voltage chart above)

2nd Det. (75) Plate Volts-P to K is 250 instead of 150

Output (42) Control Grid Volts-CG to K is 15 instead of 2.2

I've replaces all the Caps, most Resistors, and wonder what would make the CG so high on the 2nd Det.? and in turn, I suppose, the Plate voltage 100 v low on the output?
