Joe,

Pinout as follows:

1 - NC
2 - B+ in (225 V.)
3 - B+ in to the screen grids of the RF, mixer and 1st IF stages.   This came 
from the xmitter and was the means by which the receiver was muted during 
transmit.
4 - NC
5 - +12 V. to heaters.   AC OK here.
6 - Gnd.
7 - NC
9 - Audio out (600 ohms)
8 & 12 jumpered together
10 & 11      "             "

Pins 10/11 and 8/12 connected to the "Power" switch on the front panel of the 
receiver.   Used to turn the various power supplies for the receiver and 
transmitter on and off.

Hope this helps.
