Simplest Linear PSU?


Which linear power supplies can you recommend that have the least amount of miniaturized SMD and semiconductor nonsense?

I wish Audionote made a stand alone PSU. I know Weiss does, it looks good, but pricey. Looking for something simple already made to DIY with.

thanks in advance!!

Consider doing your own.... simplest? Transformer, Bridge Rectifier and filter caps..... You’ll need to do some homework.... What component are you going to use it for? How much current will the transformer need to handle. You can choose by votage and wattage rattings and get fairly close, I would choose around 4 times or higher wattage rating to make sure that you cover for 2 channels and peak current. If you are making a pure class A component, you will need much higher.  You will need to know what dc voltage that you need. Choose a transformer that is approximately 20% lower than the DC that you’ll need. So if you needed 30v, you may choose a 24v transformer. When you add the Bridge to convert AC to DC you will get the voltage boost, next choose capacitors for each channel. I’m a firm believer that the more the merrier, others don’t always agree, quoting in rush current. i have yet to have a problem here. Do some homework, if you can mod one, you can build one.
