I purhcased a ART Pro Channel a couple of years ago off ebay. Worked for a little bit, but now it stopped working. I'm trying to figure out if it's a tube. The unit powers on, I hear slight audio distortion on the output. Is there something you can do to test the tubes or is it something else?
What is that a 12AX7 tube? Plentiful and cheap. Replace the tube
What is that a 12AX7 tube? Plentiful and cheap. Replace the tube and hope that fixes it. If not it's most likely going to cost more to fix it than it's worth.
