Re: Audiophoolery?
The fourier transform of an instantly switched AC waveform includes a DC transient component, and considering the impedance of a transformer down in the frequency range of the transient, a large current transient flows which can easily saturate transformer cores and that causes problematical currents at the power frequency and its harmonics.
The ideal turn-on is an AC waveform growing slowly from zero and the reverse for turn-off. It's related to the need for a steadily diminishing AC signal and not an abrupt turn-off or removal for demagnetisers.
