Hey thanks, been away for Tday, and now back in the shack!
The 1931A I have is a metallic grey....I played with the taps a bunch...
Putting in new tubes, I have checked the coil, the dual pot on the front, (R3 I think)
and yes I have the book...
Here is what i was experiencing last week when I was playing with it:
The mod light comes on and stays on after warm up...(with or without modualtion and
regardless where the pot is set...) I tested the 2050 & it fires at 33 v, rather than
the 27 v spec....
With about 20 v inputted into the unit, I am able to peak the carrier level at the
proper point........I experiemented with the freq vs level, and it's uniform, across the freq range....any bright ideas?
