[Boatanchors] Motorola power supply

[George Babits]

Does anyone have any information on a Motorola AC power supply  TU531-5? 
Has a couple of 5U4's and a pretty hefty transformer.  Probably from a 
repeater or base station.  I would be interested in the receiver and 
transmitter pinouts as well as the connections on the terminal strip.  A 
schematic would help too.

Thanks in advance and 73,
George
