It looks like the 8ohm is exibiting the same issue. I would assume the problem is the jack as the 16 ohm jack has a weak fit with the cable end. I would like to replace the whole circuit board.
Is there anyone that can point me to a supplier of factory parts? I would be willing to send the defective one back.

Could there be an issue with the taps of this output transformer? I figured I would ask, just in cas I misdiagnosed this issue.
