3 Amp Power Supply by Karl Shoemaker, AK2O

This is the 3 amp 12 v supplies the author's been building, on a nice, painted #2 panel. The rear is showing a simple (cheap) way to insulate the pass transistors from touching and short out to the cabinet, in the event it's a tight installation setup. Otherwise, you can leave those pieces of paper off them. Remember, you can click on the pictures to obtain a larger version, should you be on a high-speed internet connection. Doing this will open a separate browser for your convenience.








 

 

 

 

 

 

As shown here with the optional insulator. You could use other materials, which might look a little more professional.








 

 

 

 

 

 

The inside (top) view revels two different versions of the AC input entry, depending on site/RFI requirements.








 

 

 

 

 

 

For the schematic go back to the power supply page and go to the "Dual supply" page for that. (It's part of that supply).
