The boards are again available, now in two variants single and dual. There is no electrical difference between the two just physical. Basically is just two boards sticking together. The faulty marking is also corrected.

Also there is a new price for the PCB.
Single PCB 2.5€ per piece
Dual PCB 5€ per piece.

Hi Ales,

I am just starting to build a DAC/Transport using a SB Duet and I think your boards would be great for the linear supplies. Is there a circuit diagram available that I could use with your board so that I have the correct values of components for the SB Duet PSU?

Please find attached schematic for this regulator.

Hi Ales,

i'm a bit of a beginner here so please bear with me 😉

Thanks for the circuit.

I need 9V regulated for the SB Duet.

What would be the best regulator to use and package type to fit the board?

Would 1n4007's be OK for the bridge, and is the 5K adjustable pot value OK for a 9V regulator?

Thanks for your help.

Hi,

The best regulator for this application would be LT1084 or LT1083 in TO-3P package, also LT1084 in TO-220 package would be just fine.

1N4007 diodes would be fine for the bridge, but with a few extra bucks you can get better performance if choosing faster diodes (BYV27, MURxxx, etc..).

With 5K adjustable multiturn pot you can get any voltage output, of course within the limits of the regulator.

Best Regards,
Ales
