I got a pair of 32 Ohm Outputs for a headphone amp. One of them had a wiring error. I had to take it apart and connect the correct wire to the correct terminal.

I got the whole thing built and one channel worked and the other didn't It took a bit but finally I took both transformers out and compared the wires and sure enough the one that didn't work was different.

I will say they sound excellent and at 180.00 for a pair of potted outputs is pretty reasonable.
