Looking for BWD 272A (power supply) repair manual

[mikie_121]

Hi

I'm trying to find the circuit diagram for the Power Supply model number 272A made by bwd.

The unit has lost voltage control and only current control produces any output. I'd love to get it going again because it has a fantastic 10 turn pot on the voltage control and a range of 0 to 50V.

Any help would be greatly appreciated.
