Hi all!
Been working on a PSU for my Exceleena 2 cab. After recapping I now get a sort of quiet high pitched noise coming from the PSU which also leaves some small ripples in the picture. This has occurred when connecting my Cadash board and other non-Cps2 boards. When I connect any of my CPS2 boards, it’s back to being as quiet as a mouse and the image looks crisp.
I looked over traces and did a reflow, it still does the same thing with non Cps2 boards. I’m feeding it 100v via a step down, as the cab indicates.
Any help always much appreciated!
