High voltage, high current super regulator, possible group buy - Page 3

What was the positive properties if you bear in mind that you don't have a grounded chassis?

Besides my thing was only the regulator.

You star ground the raw supply at its output, the Regulators and the audio circuit. The + or - leg becomes the output ground depending on which polarity you want. I've noticed an improvement in low level detail and "air" when I get rid of RF anywhere in a PS design. Galo and Jan Didden use this setup for the raw supply of any Super Reg they build.

Hi P-A,

I will buy variable regulated power supply for 50v , 20A rating. Can you make it modular ? So we can even make Lab style power supply with it?.

My first application for Pure CLASS A amplifier.

Thanks,

After that i suggest you use your amplifier for welding.

jacco that would be cool, all of us making amps that can weld, we could do group buys on audiophile crocodile clips, and super visors........

First: 20 A and 50 volts, have you thought this over? What kind of amp is this and what kind of load do you have?

This regulator will not be particulary well suited for lab power supply. You have quite different demands and ultra low noise and ultra high speed is massive overkill.

Some time has gone now and from what I can gather the interest isn't very big but nevertheless I think it's interesting as a challenge.

(I'm really puzzled by 20 A 50 V class A

How does such an amp look like?)

Big ?
I'm trying to get 500 to 600 watts out of the Krell Clones, and it is getting bigger and bigger.
Can only try to imagine how 2000 watts will be like.

Surprised too that there has not been much more response, i've read many post their wish for something that would be covered by your proposal, Per Anders.

This will come close to doing it:

A multipurpose device, amp + heat source (nice in the winter)

.... what is it?
