Pin 1 wants -7.5 V @ 30 mA.
Pin 2 wants 1.5 V @ 190 mA.
Pin 3 is common.
Pin 4 wants +3.0 V @ 360 mA
Pin 5 wants +156 (nominally) @ 35 mA.

This, per the conversion article in "CQ," Sept. 1957.

This is a "fun" rig.  As a kid I heard a W1 in California on one.

Can someone provide me with the power (battery) plug pinout for the 
TBY?  That will at least give me a start.  Looking for plugs, antenna, 
etc. but that may be whistling in the dark!!  de Jeep/K3HVG
