Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

There are some great capacitor tutorials online that might be worth checking out. There are also some really excellent lab power supply design walk through on youtube which will help you get a better understanding of how that power supply design works, and why.

For ease of construction, I use TIP35C instead of 2n3055.

Last one I did had 8 transistors on the output for 80 amps outputs... much easier with TO-247 shape... would not like doing that with TO-3... just a thought if you have not done the hardware yet.
