I was checking into parts for the noise mod for my mp-1s today and see that the TL072IN chip listed in the mod is obsolete and unavailable, what would be a suitable replacement for this ic?


What revision of the noise mod did you look at?



Ok that's an old one, get a OPA2134AP for U4, don't change U9. Now the TL072 is not obsolete at all but the OPA is better.
