Hi i have a Sherwood AX7030R amp and im having trouble with the balance knob. The left channel is a lot quieter than the right and when i turn the balance knob it makes a crackle sound. Any help would be great
No i have not tried cleaning it yet. I have taken it all apart now, no sign of any swollen capacitors or anything. Its actually pretty clean inside. Are there any test i can do to see if the knobs the problem or if the problem runs deeper
