GCHA (Only One Channel Working)

My GCHA has no sound out of one (left) channel (and the right channel sounds fainter/less dynamic than it should, but that might be in my head…).

The same issue exists with both the USB DAC input (which I never use, but did to test) and the RCA inputs. I don’t have XLR cables to test the XLR inputs.

I love the amp, and had recently bought an HD650 specifically to pair with it so I want to get it working! :slight_smile:

Any ideas?

I’m happy to send it back to Colorado but thought I’d test the waters for possible issues first.

If you have swapped output cables to make sure the same channel remains dead, thus making sure it isn’t the cables themselves, then you will need to have us take a look for you.
