I have used JLM Audio AC/DC power supplies on my builds, a Neve clone 4 channel pre amp and a Trident 80B clone EQ, they are still running after 12 years in a studio.

I'm having trouble finding the Bill of Materials... Could someone point me to it, please. This looks like a perfect solution for my planned BA2018 linestage / Pearl 3 project.
Thanks. Don

Don,

See the pdf attachments to post #1 in this thread for build docs including BOM.

The raw psu board that will be included in the pearl 3 kit is a similar board to this except it won’t have the regulators. Pearl 3 has the regs on the phono stage boards. Of course you could do pre regulation in the psu box at 18 or 20v, and then the p3 takes it down to 15v. Up to you.

Doh! I see it now, bottom of the build notes. Thankyou.

Hi Randy,
I am looking for a single rail ac-dc power supply. I have 9VAC secondary and would like +5V,500ma DC output. Will one of your FlexReg single rail supply's work for me ? Also PM'd you.
Thanks,
MM

Thanks for making this. Are you willing to share the PCB files for both the single and dual rail designs so that I can get the boards made locally? I'm assuming that the boards are designed using KiCad? I've been using KiCad for many years so no worries there. I hope you can help? Thanks.

I'm not posting/sharing gerbers for this board. I'm happy to ship PCBs to UK. Drop me a PM if interested.

Randy does very nice work. You won't be disappointed.

Hi, can I change the values of the 0R51 resistors between the capacitors? What resistance values can be used using 4700µF capacitors? Thank you
