Adjustable Dual Polarity Power Supply

flemmng
flemmng over 7 years ago

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
