Re: [sdiy] +-12V supply

if putting 723 instead of 7812 is an overkill, how would you call someone who made 1.5A power supply using regular opamps, darlington transistors, lots of other components, and 10ppm/K reference IC, where LM317/337 would be more than enough?

You're right, a crazy maniac.
But I just wanted it so bad.

BTW, IMHO 78xx and 79xx suck
