Really strange issue with this one, not sure where to start.

It powers up and produces audio fine from channels 2 and 4 but when you apply signal to channels 1 or 3 with a load it protects and you hear the transformer buzz a little. It does produce a split second of distorted audio before protect kicks. There is no significant DC offset on any channels and the two channels seem to have identical symptoms.
