Digital-
Hear me out. I am not very knowledgeable about the various descriptions used to specify some of these parts.
Yes, I know what a capacitor, resistor, potentiometer is etc. but the variety is not my best subject. The building of this regulator calls for a polarized cap, and I just would rather not mess up. If I knew all the ins and outs I could substitute, but I just don't. Now if we were talking about substituting a circuit breaker or a motor starter for you house or factory I can improvise in a second. But in this case I am a little confused.
Heck Radio Shack didn't even have one, maybe a different store?

Go here to see what I want to build using the LM 350, for greater capacity.
