[MRCA] Power supply? Fair Radio

[mr3hi8st8or5y at cox.net]

Just picked up an 11A33; at least that is the number on the olive green front under the black pull handle. Is it an AF power supply? It is a plug-in module. The top line reads 115v - 50 - 400~. It has red pin taps for +24v, +7v, both at 1/2A and +12v at 1 & 1/2A and +4v at 3A. It has purple taps for -12v @ 1 1/2A, -6v @ 1/2A, and -4v @ 3/4A. I think it is AF because on the side it says "MAX. ALT. 10K FT." If you know what this is please contact me.
Does anyone know if Fair Radio will again have a tailgate sale during Hamvention?
