It has been more than 50 years, but I recall I had the assignment of 'AN/SRC-10-11-12' series to U.S. Navy used U.S. Army AN/VRC-8-9-10 radios in shipboard use. I had developed the associated 115VAC power supply, PP-1175/SRC for ship use vice the DC versions to eliminate the need to install a DC power source.
