Hi P/A,
Built the supply and it sound great! I use it in my Hiraga 50Watt Class A amp instead of the 22V zeners. Perfect job! Thanks!

Just closed it up and listening to it right now 🙂
I'll open it up shortly and make some pics! 🙂

So what is the max current capability of this PSU?
Crap! Did I miss out on these?!
I'm looking for a +12V and -12V version
Documentation is not verry clear/accessible. Click on the Link in one of the messages of Peranders. Then you can download the BOM for all the versions.
Oops... This is both + and - on same board...
I need to get the pcb's as well as the BOM.

Can't edit posts...but,
What is minimum required input voltage for regulated 12V output?
I plan on replacing my 78xx and 79xx regs on my soundcard.
Wondering if I'm going to have to use a clean external PSU to power this.

Amps
I don't need much amps. For me about 500mA is more than enough. And that's easy for the SSR03.😛
Posted the schematic. The -22 and +22V are from the SSR03.
I need clean input stage voltage. This is much better than the original zener witch provided the 22V on the board.

You need a 2 x 18V transformer to feed the board for +/- 12 volt.
Received my boards yesterday. Very impressed with the quality! Can't wait to put one together.
Thank you

-+8V regulation...would this be possible with 11.5 to 11.8V input with proper component selection?

I've been trying to make an informed descision about LM329 vs LM431 - the datasheets can't be really compared as they are have different working principles. Both specced @ 50ppm/C. Which one should be the preferred type?
PA,
Any spare left from 2nd run? Love the boards from 1st run and opt for a couple more (call me greedy) -)

PA,
I was not paying attention, if you have any extra I would like one. No big deal just for my stock for a future project.
