[Milsurplus] Need AN/GRC-9 Assistance

Gentlemen,

Can someone scan the transmitter voltage/resistance charts
for me?  My manual is AWOL, and I'm working solely from the
schematic in the case.

This set was working FB about 2 years ago.  Now I'm not
getting enough grid drive to the 2E22 to hold in K102A. 
This relay apparently removes the screen-grid voltage from
the final in the absence of grid drive.  It does work, just
barely, on Band-3.  Gross things like plate and filament
voltages seem ok.  There is RF grid drive, just not enough.

Any help appreciated.

73,
Al
