Collins R-392 / URR Original 9 Pin Power Connector NEW
This Collins R-392/URR Amphphenol "UW 1220FB23" original power connector, is New old stock (not new in the original package).
This hard to find power, audio and control connector, is used with the R-392 / URR (J-103)
This (9) connector plug is also used with other Military Receivers as well.
I have only a few left and they may have some marks or small scratches.
The J103 connector is used to provide power to the R-392 receiver and to provide control of the optional companion T-195 transmitter.
