Final state of the mains side:

Closed lid:

The thing powers up and gives out the expected voltages without a load/Amiga connected. Now I'm getting a reading of 80V AC from all rails to the shield pin/earth which stumps me a bit. Need to think about how to proceed before connecting anything to that.

I think I might need to connect the secondary side ground to earth as well, I presume it was like that when it was housed in its original casing through the chassis. Measuring any rail of my PC PSU to ground gives the intended DC voltage without ripple, so I think thats the norm. The current reading of the Zalman is 0V DC to earth along with the 80v AC.

Yes, looks like you need to manually connect the secondary side GND to earth, when running it outside its metal case. Voltages are okay now. Now for a test run.
