Onegraph WG300 Power Evaluation Monitor repair.

[aargee]

Hi all,

I have an old Onegraph WG300 that has decided to short out one of its secondaries in the power transformer.
Before I send it to e-waste I thought I'd see if anyone had a service manual or schematic for this device.
The PCB mount transformer is part of a linear power supply on board and is a custom part. It has 100-115V and 220-240V primary windings with two secondaries, one of which is shorted internally.
Looking at the circuitry hanging off it, it's possibly a 24V winding or there-abouts.
