Today's winner of the not-so-coveted ORT NoK award...I don't understand your concern at all. The output stage of an OTL is essentially a cathode follower with a voltage gain of less than 1. Cathode followers are very stable, and are used in many pieces of test equipment because they have stability independent of load. Since the cathode follower is running in the Class A operating region, the load on the power transformer is the same at zero signal or full output, so the secondary of the transformer sees a constant load. Since the primary of the transformer is connected to the power grid, it's inherent impedance is so low that anything we do on the power transformer secondary is orders of magnitude below what would disturb the primary. I think that you may be talking about certain Single Ended transformer amps.
In other words, I have no real clue as to what you just said but will nod my approval as if I actually did, hence the NoK, aka: the Nod of Knowledge!
And I honestly believe you as I have left my former Valhalla 2 on for hours sans any load. Not for purposes of "burning it in" but because I am forget full. No harm has ever been noticed in either musical reproduction or melt-down. Yup. It is da Schiit!
Huzzahs to you, sir!
