Adjustable Dual Polarity Power Supply

flemmng

Im looking for DIY kits or schematics for a  Adjustable Dual Polarity Power Supply

I know about the LM317/LM337 setup but i wonder if there is something better than that, so far i haven't found anything useful

I don't really need high precision or super specs, just a hobby supply to revive my old interest and skills in electronics

Please advice

    A very fine "box" you put together there. Looking good on the inside too.

    I do agree with your thoughts on that -why reinvent the wheel again.

     

    I might have used a different layout on the front, placing the units on top of each other instead of beside each other, that would have made room for bigger knobs

    I found those boards too and along with some other interesting kits, still waiting for delivery.
