Hey Team,

I'm looking for opamps with the following properties:

1) Through-hole
2) Quad opamp
3) 14-DIP package
4) High power range (+/-18V, say)
5) Low input bias current (10 pA or less typical)
6) Pin-compatible with TL074, etc.
7) Not LF444 (cuz they all seem to be defective)

So, basically, I'm looking for a suitable alternative for LF444.

So, here are my questions:

A) Do you know of such a thing
B) How does one go about finding such a thing, generally?

Thanks in advance!
Dave (Floating VCA) Dixon
