You would turn them around and connect the secondaries to your AC wall outlet and the primaries to the filter section of a power supply and other words 120 V in and 480 V, or whatever the voltage is, out. You could use that to power some unimaginably large amplifiers. But otherwise, why bother? It’s the turns ratio that limits their usefulness in audio.
can large (>10kVA) industrial transformers be adapted for use as audio trans
i have access to several surplus transformers all of which are between say 8kVA and 50+ kVA. they are all bulky, heavy and pretty much stationary once moved into position. i really have no idea what im talking about, but is it possible, or even beneficial, to somehow adapt these transformers for audio use?
