Post Subject: I was speaking of amplifier output stages, generallyPosted by rickmcinnis on: 9/26/2022
Unless they are quite unusual I doubt your amplifier's output stage uses regulated supplies.
My point was that PUREPOWER/Inverters, etc. deliver a far more constant AC voltage than the line and that this could be a reason people find them to be useful. They have stabilized the voltage on the output stage. I assume most high quality amplifiers these days are employing voltage regulation on the input stage/s. Though the MELQUAIDES amplifier has no voltage regulation other than chokes and resistors and I safely assume it is a very fine sounding amplifier. But I would wonder, without PUREPOWER as the source of its AC, would its sound be compromised by more than AC junk but by the inconstancy of the voltage?
I went from there to speculate that this same quality might allow one to NOT use regulators which can mess up the sound compared to good old chokes. At least in audio lore this is the case and is quite obvious when one is speaking of three terminal regulators.
Would a constant AC line voltage negate the need for complicated regulators in ;pw level voltage amplification circuits? Have no feel for how this could affect a digital circuit.
To end, I must admit I am not quite sure what you are saying but hope the above clarifies what I intended to say.
