I can't see a proper earth on that thing.

The earth is soldered directly to the side of the transformer.

Gaugemaster do nice new ones with a lifetime warranty.
I bought a s/h four channel one with one faulty channel and sent it
back and they repaired it without question.

Gaugemaster are good, but not enough amps for 0 gauge. Bench power
supplies are great, 0-20v (some 0-30v), up to 5 amps. The Powermaster
supplies 0-12v up to 2.5 amps, which is plenty for most locos, and far
more than a Duette or other, similar, later models.
