[GreenKeys] Off topic: variable transformer

[Dave Wade]

As others have said, if its not very old, then a Variac is not of much use
as switch mode won't work at all, and linear may just drop out.
I would try and test PSU separately but note that many older switch mode
power supplies require a load in order to operate correctly.
