PSU 15V 22A

My very first project as an amateur radio operator was a power supply unit. It is transformer based. And i build this from the schematics from the net. Also i did not have knowledge of UV PCB back then, so it was build on a vero board.... Not recommended. I added a volt and ammeter not in the schematics. The volt meter is connected across the +ve and -ve DC output and the ammeter is thru the DC +ve output. Also i recommend a bigger or 3 or 4 22000uF capacitors in parallel and a 18V 22A transformer instead of 15V.

To those who want to built this here are the schematics or you can get newer designs from

This design is no longer available on that site. Below my finished product.
