Rich,

There were a couple of different AC supplies for the GRC-9 but these items 
are rare and expensive.   Were you looking for a manual for one of these (also 
rare), of just the voltage/pin listing for the connector on the front of the 
transmitter?

As someone has already mentioned you'll need a manual if you're going to do 
very much with this set.   The original is TM 11-263 which also covers the two 
dynamotor supplies (DY-88 & DY-105), the PE-237 vibrator PS (not recommended) 
and the hand crank generators GN-58, GN-58A (early) and GN-58A (late).   You 
can get a good repro manual from W7FG, http://www.w7fg.com/index.html.

Suggest you tune in to the Military Radio Net, Sat. mornings 3885 KHz, 0500 - 
0700 (approx) EDT.   Net control is Ted, W3PWW.   Guys there can give you 
lots of help with this set.

Good luck,
