[MRCA] Was R105D, now AM-723BB/VRC

Thank you to everyone who responded on the power for R105D question. All solutions were forwarded to the guy that asked me. So he took it to a TV repairman who could not help him.
This week end I again drove a vet in his Jeep with my granddaughter on the 50 cal. At the show my display honored RTOs that served in Vet Nam. It included that PRC-77 I mentioned toW3PWW and photos of RTOs in combat (TNX to Joe, WA4VAG) . 
At the show I picked up an AM-723BB/VRC Amplifier Radio Freq. (stamped CRAC, two BNC connectors on the front marked J1-ANT & J2 MV/RT and a P1 14 pin connector on the back, green). No results to a Google search. Anyone recognize this piece of equipment?
