This listing is for (1) BRAND NEW Cannon ORIGINAL 22 pin Female P1 Plug, for the Collins ARC-73 Transmitter. this 22 Pin Connector is Part # DPA-24C2-33S-6I am told this is the connector on the back side of the ARC-73 Transmitter.This is a great find and is probably the hardest power connector to find as they have long been discontinued! It has the two coax connectors built in and the pin contacts are gold plated.This one is Brand New, and is complete with the shell. The (2) Coax pins are unused and are held in place with red plastic keepers so they will remain in place till you solder them onto the coax. My cost on this connector was very high due to how scarce they are.Do not let this one get away!
