Are these direct-drive OTL amplifiers? Oh, I guess you did mention they are from your Acoustats. Very cool. I use Beveridge 2SW speakers in one of my systems, also direct-driven. Although such amplifiers do put out high-ish voltage, sometimes the output voltage is much further increased after the secondaries, by use of voltage doublers, which is at the expense of current. But very very little current (at very very high voltage) is required to drive an ESL directly. Anyway, whatever one might have expected in terms of the effect of the AC voltage on vibration of the transformer, I don't doubt your direct experience. And those are probably unobtainium transformers, should one of them blow, so you are right to be conservative. I feel the same way about the power transformers in the Bev DD amplifiers.
