Need: Schem. for OLD NJE Corp. Power Supply

[Steve]

We have an old NJE Corp Power Supply
Model # SY36-30B-M-D1268
The front panel has " Model SY 36-30", " 18v 0-30A"

There are 2 meters 0-40Volts and 0-30Amps

The unit has no tubes but has germanium transistors

We were able to get it working but would like to find
a manual / schematic for it.

Thanks
Steve
