PS100 Not Attenuating or Channel Switching

Hey everyone! I am exited and pleased to announce that I solved the issue and successfully repaired my unit. As suspected, R406 and D406 failed. I replaced them and put it back together and back functioning as normal. Here’s a video demonstrating the issue, repair, and play test. Hope it helps anyone with the same “stuck in bypass mode/ not switching channels/ non functioning knobs” issue. Thanks @dan for the help!!
