I need an op amp that can handle +- 28 volts rail to rail. I plan to drive a
couple of transistors in an emitter follower configuration to build a small
audio amp.
TIA

Built one like this once before, wasn't a great amp but made a nice PA amp.
I was going to build one for my auctioneer friend. I had the amp for a long
time before I sold it, just cant remeber the op amp I used . Pretty sure it
was an ECG unit, ECG/SK was the only thing the parts jobber sold. Dont have
an ECG book anymore though. Real simple circuit, a complimentary pair of
Darlington transistors used on the output. LM12 sounds like it may be what I
want.

Thanks, found my notes on the one I built years ago. I used an ECG 925.
Looks like I will have to crank the power supply back a bit.This one will
only handle +- 22 volts rail to rail. Hope I can still get them. Thanks to
my well supplied "junk box" a 24' by 24' two story garage I havent had to
buy a part in years, . Well not at the local parts store anyway, but dont
think I have this one.
