For a BK Precision 1730 Power Supply (*not* the 1730A), I'm searching for the service manual, or at least the schematic.

The unit has two relays, and looks to be auto-ranging to reduce power dissipation in the output devices. At random times the relays start banging away and the output becomes - unsteady. Smells like a bad voltage adjust pot, but I'd like to see the circuit before I go climbing around in there.

Thanks.
