[Milsurplus] WRC-1 power supply question

[Jim Whartenby]

Picked up a T-827B exciter that is missing the power supply circuit
board (2A2A8)and a relay (2A2K2).  Already have a R-1051B organ donor
which has the power supply board (1A2A8) and several similar looking
relays

Seems that the power supplies appear to be electrically identical but,
unfortunately, they look a lot different in parts layout and the
connection to the wiring harness is on opposite sides of the board. 
But the board support standoffs look spot on.

Anyone have any experience with transplanting one power supply board to
the other?
