ACA will run on ~15V to ~30v, so no need to look for exactly 24.00V.

What's C9 and R8 for?

Ian, did you ever read Rod Elliotts article concerning a "CapMultiplier - PSU" as the ACA's PSU?
Capacitance Multiplier Power Supply Filter

I did! And I have built one, connected it to my ACA and have been absolutely astonished about
how much superior the sound has been compared to a wall-market PSU, to a SMPS, the forum's
proposal, ...

It is your decision, it is your ears - Rudi

P.S.: Find attached a PCB look-through of the CAPMx PSU that I am using to power my ACA!

Wow. Thanks. I'd never heard of a capacitance multiplier!

This might also be a good experiment for my valve phono stage.
