not + - supply ? You blew my meager mind for a minute, but I might be beginning to 'get it'.
So P102 is to zero the offset, right? The circuit stabilizes well enough / fast enough for no danger?
If I built it I'd probably replace P102 with fixed resistance after determining the value(s) - unless I've got it wrong, which I probably do
sorry to be such a pain, I'm just so dang rusty (and thick headed).
Thanks!
Maybe something like this.
Mean Well MW NES-150-24 24 VDC 6.5A 150W Regulated Switching Power Supply
How are you doing this? It looks like the super regulator is limited to +/-15V or so, or +/-19V at the outside.

I'm sure It's wonderful!
Somehow I have found the smoke in every shunt type PSU with more than one device in it! I'm Jinxed with the things. More simpler just makes me happier - like a BOZ type with a big hammer swing of capacitance
Thanks
B1 R2 up and running
Had to build one of these (see post #17), and I'm happy to report that it sounds fantastic, even though I'm temporarily using a 10K rather than a 25K pot (it's coming). It's at least as good as the stock B1, and much better than the DCB1s I built (which, to be fair, sounded good in some setups but not others). Warm sound, with tremendous bass. Here's some pics of the current state of things, and I'll post more when it's finished. The transformer on the board is to power the relay coil for input selection - I used it because I had it laying around. Haven't hooked it up yet.
The power supply is a Salas shunt with about 300mA spare current.
Sorry about that. I did wonder why the product seemed stale in
the marketplace...
Here's the schematic.

Very cool. I plan on integrating the circuit into a project. Nice to 'hear' it works well!
(as if there was a doubt.)
What is the voltage of your PSU? and is it a single supply?
Is this circuit sorta hidden in this thread?

Where, prey tell.... is that recommended?
Mr. Pass stated that he used a single 24v switcher.
TIA, and please pardon my confusion.

Yeah, you missed my post.
I'm pretty sure I read them all. You suggested many circuits from shunt to chip, and even a Mean-Well switcher. No place do I read that the recommend PSU is +- 24v.
The only absolute specific that I see, is that Mr. Pass stated that he used a single 24v switcher.
In the friendliest of ways I ask - not the least combative.... because I am now confused.
