Amiga 600 Power Supply

An Amiga 500 psu would be better, because they are higher quality and put out more wattage.

Please, don't spread that myth.

Old, heavy A500 PSU: 2.5A@5V - avoid if possible
Newer, light weight A500 PSU: 4.5A@5V
Light weight A500/A600 PSU: 3.0A@5V (the same as the A600/A1200 PSU)

Yeah I forgot to say I had no luck when using the Shield GND, had to put the NEG probe on 0V GND instead.

Retested and got the following results:-

13.80v
-14.25v
5.29v

Unfortunately, I don't have a spare PS to check

It should read +/- 5%. That is:

11,4 - 12,6 volt
-11,4 - -12,6 volt
4,75 - 5,25 volt

Get another A500/A600/A1200 PSU.

Not a myth.  Why do you think Amiga 1200 owners buy Amiga 500 power supplies?

Not all, but _some_ A500 psu:s put out more wattage on the 5 volt line. You have to make sure you get the right model, that's my point.

2.5A x 5V = 12.5 W
3.0A x 5V = 15 W
4.5A x 5V = 22.5 W
