So. I do tend to say that the old brick psus that come with the C64 are usually ok and pass all the 24 hour load tests I put them under.
However, there is one which I will exclusively NOT connect to a 64 without testing or inspecting.
The first pic is the voltage it supplied on the 5v line when I first connected it to my tester. 7.7v! That will hurt your 64.
The second pic is the symbol to look out for on the bottom of your black psu. These are UK made and I suspect only sold here with later breadbins. It says "Woden".
The third pic is why they fail. A dry joint on the ground pin of the 7805 regulator. It disconnects and the output floats. Hence the 7v.
Just keep an eye out. This is a Commodore health announcement brought to you by @commodorelad
