Op-1 Volume Knob stopped working


#1

Somehow, the volume knob on my Op1 stopped working. It does not feel mechanically damaged, still turns, but no change in output volume.

Anyone else seen this?


#2

1 obv plug in headphones and take them out and try again
2 play something that goes to max level (say radio in), turn the knob all the way up, does the volume increase gradually at all? mine used to do that, I emailed TE, they said it’s normal.
