In the Thread: Devid Berning amplifiers: the anti-trnsformers frenzy?
Post Subject: One obvious benefitPosted by Paul S on: 9/24/2007
Well, this certainly shrinks chassis size, if nothing else. I've never looked at the circuit, but there has to be some sort of transformer function at each end, up and down, and the easiest way to do this would be with transformers ;>
. If the speaker load straps to a step-down device that has its output modulated by the signal...
As I said in a response to Merlin, I seem to remember the wild and crazy Bob Carver also came up with some sort of switching PS that he used to claim all sorts of amazing things for. This was decades ago. That amp truly sucked.
I does look like the Berning is some sort of "D" variant, at least in terms of the "switched" PS, although there must be something "novel" there to get the patent.
The patent refers to "push-pull", which I would take to mean PNP SS in the PS in this case, given the SET signal path.
To my ears the thing sounds PP, however. Good, but PP. I could live with it.
With respect to the previous thread, the idea of "one size fits all" still applies here, I think, along with the usual ramifications that implies.
Best regards,
Paul S
