Y-Not Buffer Location

Kurt May

Quick question: is the Y-Not buffer located at the input or output?

Put another way, is there a buffer driving both outputs A and B? Or just on Output B to help drive the transformer.

It's at the input, so will drive both outputs. The exception to this is if you have the TRS Input switch turned on. If that's the case, only the A side (the tip of the input jack) is buffered.
