Random electrical engineering question. I am looking at building an RIAA preamp (for a record turntable), and most of the circuits out there use a NE5532 dual low noise opamp.

However, I have a LOT OF 4741 opamps (a lot). Originally destined for the L1011 aircraft, lol.

My analog design skills having significantly atrophied since college (cough cough), what specifications on an opamp (aside from noise) are important for this stuff? I suspect I have to re-calculate gain and values for a different opamp? (also, bandwidth on the 4741 is 2.5Mhz... NE5532 is 12Mhz... so I assume they aren't going to be equivalent).

@ai6yr I have no idea what the answer is, but if you can make it work, that be a fun side business!

@ColesStreetPothole LOL, I should know this, except that part of going to school studying electrical engineering has not yet awakened in my brain. Considering I forgot to roll out the recycling bin to the curb for trash pickup last night, I don't have high hopes for the analog design neurons working so quickly 🤪

@ai6yr 😆 It's garbage night here and spouse had to remind me. Eventually, it would come back to you, but who has time for that? 🤣
