OPA2604AU replaceable with a TL072?

[J M Fahey]

if they could have gotten away with using a tl072 they would have.

Good point.
Besides, they used quite a few of them;the potential cost saving could have been important ... and they didn´t.

Yea i went ahead and bought the OPA2604's. Finished the amp and its running like a champ. Glad to have that one out of the shop. It didn't have a lot of big problems just a few insidious ones.

Linear Technology makes great OP amps with good stats.........
