Thanks Redwire. I am fortunate to have a brother who has a workshop where pack cups, medals, plaques, etc.. and where can I retrieve the remains of production and where can I access the machine to engrave aluminum. For the rest just a bit of skill and imagination

I finally finished my PSU in version 5A. I thank the community for suggestions and advice, especially Audioguru and Redwire that with their skill and patience have developed this project. Greetings from Italy

Audioguru Thanks for the advice. Proceed to build the new project. Do you know where I can find the PCB in PDF format or JPEG updated?

I built the old version with TL081 long time ago and I update it without changing the PCB following these instructions, or is it better to redo the PCB with the new version? Sorry for my imperfect English
