Default Re: Distorted image with Commodore 128

I'm pretty sure the C128 used a sort of hybrid power supply with a switch-mode supply for 5V DC and a transformer for 9V AC. I'm sure I remember loose laminations in these when I repaired computers for a living (though it was some time ago, so my memory may be playing tricks with me!)
