As noted below, the Berning ZOTL uses passive parts, i.e., inductors, etc, not active solid state devices, to achieve a transformer-less output. The best explanation of his circuit I ever saw was in a 2-part article by Charles Hanson (I think) published in Glass Audio just before the demise of that lamented magazine. I understood the circuit then, but I would not want to try verbally to re-construct the concept now. IMO, it is rather silly to argue whether it is a "true" OTL or not; the question is whether it sounds good, and I think it does. I do happen to prefer my Atma amplifiers, howver. Berning is clearly brilliant, in any case.
