[Milsurplus] National R-1230 countermeasures receiver

[HL]

Wanted: manual, schematics for National Radio Company’s 1963 countermeasures receiver, Models R-1230 (aka: R-1125 or AN/FRA-11 or AN/FRA-54). (Manual ID: NAVSHIPS 94581) I think I can deal with its 65kHz IF output, and I can provide the needed power voltages, but without a schematic, I am stymied by its ten-pin power connector and need pin IDs for 175VDC, 6.3VAC, 18VAC, 5VAC, etc. Would love to get this wonderfully built, complex beast operating! Any info will be appreciated. Holiday greetings, Hal KK6HY
