Mechanically/operationally, nothing wrong, the amp is in good shape cosmetically.

This is also a revision 1.5 model from what I can tell.

Please read on.

I bought this recently from USAM second hand. My reason for sale is a little silly but providing full disclosure so it is not a surprise.

The volume knob on this one is set a little out of place; visually the indentation on the face of the knob makes it look like you are at high volume when in fact you are at minimum volume.

Visually, we are talking about a tiny dot that even on a good day is hard to see. In my images you will see what I am talking about, volume is set to minimum in these pictures (see image 4).

On any given amp you can undo the screw holding down the knob and set it where you want it. In this amp, the set screw seems glued or stuck and I can't get it to loosen. Since I don't want to deal with this madness, I'm putting the amp up for sale.

Asking $600 plus 20 shipping (basically splits the cost).

Schiit could repair the knob as well; they quoted me a basic repair starting at $40 but shipping will add to that.
