How to find notes?This is not distortion, this is interference from switcher, please read Jan's notes
Thanks for the advice。I designed that power supply.
But the DC-DC converter is not 'weak', if it burned out you have a problem in the amp.
Replacing it with something else will not fix the problem.

I found a patch missing on the reverse side of the board? Must the patch in the red circle be made?
Yes, do all of the changes mentioned here: https://docs.google.com/document/d/1Msi3JuRKVNsGa9yKPpHD9AH9sX4urQjUuti1efcf5AM/edit
