hmm this is really interesting, I actually have tried almost the same circuit (different values) in the simulator (falstad) but it didn't work. Op amps I have offered in simulator's menu: LM324 and LM741
I understand the theory in this circuit but it seems I need to find suitable real-life op amp model. What values should I look into when I read datasheets of op amps for this application?

Also why are you using polarized capacitor as C1? It can get damaged because of AC signal, am I right?
