	I'm looking for pin-compatable replacements for 1458/4558 op-amps.
It's for an audio application, so I'm looking for the best frequency response
(secondary) and the lowest noise (primary).  I intend to buy a few different
types and play around with different combinations, so I'm trying to find a
variety.  Are there any ones that have a FET *output* stage, or don't such
things exist?  I'd also like to get addresses for places from which I can order
these.  What I have so far is:
	TL082 (available from Radio Schlock for 1.98, any mail order?)
	Analog Devices AD712 
Much thanks.
