GFR	Re: Substitute for 747 op-amp It's two 741's in the same package, as if just one wouldn't be bad enough If you're doing the board layout just use any other dual opamp like the 1458 or TL072 or TL082 or 4558. If not try using the "dead bug" technique that's on RG's site (www.geofex.com) so that you can use these chips. Believe me there's nothing magic about the 747 it's just a source of noise and crossover distortion. Any of the alternatives above is much better.

Believe me there's nothing magic about the 747 it's just a source of noise and crossover distortion. Any of the alternatives above is *much* better.
