You can really use just about any op amp, even the old 741. For that one the output is pin 6, not pin 1, & the V+ supply goes to pin 7 instead of 8. I recommended the TLV2372 or LMC6482 because they're less prone to crossover distortion. If you want to order the good ones: TLV2372: Digikey: 296-12219-5-ND $1.30 Newark: 76C7976 $1.30 Mouser: 595-TLV2372IP $1.30 LMC6482: Digikey: LMC6482IN-ND $1.82 Newark: 41K2662 $1.92 Bob NO6B
