I am looking at your CA-PSU and wonder why have you decided to exclude connection to regular ground(earth) ? I am not an expert, just old fashion guy, that is more use to having computer connected to house earth wire.
Also I have original Amiga 1200 PSU and got weird reading on Ground and Shield. I expected only one of them to have zero resistance between earth wire and them. I would expect zero resistance between shield and earth wire on 240V side ? Both show zero resistance to earth wire. Is this normal or is CAP out of order ?
Amiga boots and works on this original PSU.
Thanks and BR, Luka
