Sounds nutty huh?
I was just wondering, with the discussion that went on about switching and linear PSUs, how much noise they actually make...
Since the potentiometer doesn't affect the gain of the amp, would the same amount of PSU noise be heard when the pot is at minimum as at maximum?
I.e. I just turn the pot on my Porta Corda above the off position, and I immediately hear all the noise I will ever hear due to the PSU--any noise above that when I crank the knob up would be due to other noisy electronics inside the amp.
True?
Well I hear just about nothing with the pot on min. and nothing connected to the amp's inputs, with *any* PSU I've used, even the unregulated one--is this an indication that PSU noise is not all that it's cracked up to be?
