Why not just compare the working channels to the bad one? There's likely either a dual op amp for each channel, or sometimes two channels will share a dual op amp (half for each channel). Some of your channels work and one doesn't, so you have proper voltages on enough channels to use them for a reference. If it's an op amp, I'd expect there to be DC on pins of that IC where there shouldn't be.Originally posted by guitardad View Post"I took a photo of my ohm meter... It didn't help."

He shoots,...... he scores!
Unfortunately, it looks like the power supply and amp are not included.
Maybe we don't need that here. It depends on if guitardad's "distorted channel" means power amp channel or mixer channel."I took a photo of my ohm meter... It didn't help." Enzo 8/20/22Comment
