Hi, as I’m not proficient enough to test the ripple on the supply voltages, I got another power/amp board from a donor unit. 🙂 Swapping the board does not have any effect on the problem. I guess the new board could have the same problem, but it’s quite unlikely? I have also swapped all of the electrolytics on the pc board, but the problem still remains. The 2,5v on the reset line still bugs me. Is it correct? If not, what could be causing it?
