[ARC5] Wanted to exchange. Neat command power supply for connector pins.

Les,

Before you go to all the trouble to fabricate a complete connector insert 
from scratch, are you aware that the three plugs in the receivers onto which 
the RF coil rack is mounted are the same pin circle diameter and pin spacing 
as the outer six sockets in the receiver's rear connector?  All that you 
have to do to make the electrical part of the external power and control 
connector is to add the center pin.  And if you wish, fabricate the backshell.  
So each basket case ARA receiver and each basket case A-model SCR-274-N 
receiver will yield plugs for three receivers.  I say A-model because many (but 
maybe not all) B-model receivers do not have all of the pins installed - only 
the ones that are used.  Of course if you had the proper pins, you could 
also populate the empty holes, too.

Also, the IF transformer plugs fit the AN/ARC-5 transmitters.
