NT Preamp Boost: correct IC?

[MathU41]

Finishing up a boost. Can’t get it to work with the TL072 the BOM calls for, but checked the notes, they say to use a TL061 or TL071, and it does indeed work great with a TL071.

Comparing diagram and pinout, and the circuit’s outputting on pin 6, which pinouts for TL072 say is the second input.

Just checking if I’m catching flukes of errors on my end, or if the BOM is incorrect and the TL071/TL061 would be the correct IC.

That is definitely a typo.

Also since it works with a TL071 that is also a good sign 😉

Thanks very much for letting me know. Build Document corrected.

No problem! I just wanted to confirm since the TL072 seems to be pretty standard in most of your other circuits.
Plus, if anyone else has issues with it and do a search, maybe this will come up. Helping future builders.
