Do you still have this amp for trade? I have a 2010 OTS with half power switch on the rear panel, and OD trimmer there as well. I have the Kleinulator (NO Power supply), and dark green levant head cab by Swanson OR dark green 1 x 12 combo (matches head) by Sourmash. White or Black chicken head knobs I have both The combo has WGS speaker. If you are interested tell me more about yours.
I still have it, and it sounds amazing. I posted some YouTube videos recently. I'm really, only going to consider loop+head+2x12
I've seen a few deals like this around, but they were too far or I was too late
