Quickie: Are the OPA2228(dual 228) drop in replacement for 2134?

I'm ordering the parts for my Hansen board, and Digi-Key (as usual) is out of stock on the 2134s. The in-stock replacement, the 2132P, is $8 (!) a piece, and I need four of them. SO, since Digi-Key is IN stock on the dual 228s, I'm wondering if I can use them as drop-in replacements for the specified chips.

Quickie answer: Yes

And 2132s in DIP are going, so $8 or not I'd get some if you can afford them anyway.

it should be okay, but it may oscillate if the gain is too low.

JOOC, what does it mean for an amp to oscillate? You mean make that "testing one-two-SQUEEEEAL" noise?
