The LM338 works quite well. Simpler means fewer parts to fail making
higher reliability.
Given the choice, I went with the LM338. Several times...
Build the power supply, then you should acquire a S/N!

Hi,
I'm going to be building a power supply for a K2. I have two
choices for regulators from the junk box: an LM338, T03 5A
adjustable regulator, and a complete PCB based on the LM723 with
external pass transistors. I have a torodial transormer that can
supply 3A continous.
I'd like to use the LM723 board, but I'd also like to save it for a
more complicated supply (like for the KPA-100). For some reason, I
don't want to trust the LM338, its just too simple... Performance?
Reliability? I can't quite grasp the possiblity that I can get a
decent supply with less than 10 parts!
Thanks & 73,
Dave AA3EE
