RF-111/TRC-75
All the above components are inclosed in the case CY 2600/TRC-75.
The power for the TRC-75 is from the inverter PP-2352/UR.
wich convert the vehicular 28 Vdc to a three phases 115 Vac 400Hz ,
one phase is filtered for use with the receiver R-761/ARC-58 and for the various servo amplifiers used in the apparatus.
