I've got an (car)amp and this are using the "old" HA4741 op-amp in the input/ filter stage.
The sound from this amp is so and so...
Considering the "741-family" not very good for audio-use, I want to replace theese op-amps...
I was thinking about MC33079. I can get theese from SGS-Thomson, and ON-semi, would the manufacturer have an inpact on the sound ?
Is there any other Quad op-amp's available that would be better than the MC33079 ??
Lyra 😕

Bear in mind if it's using a quad 741, sticking a fast opamp like the OPA4134 in there could be asking for trouble...
I'd stick with the TL074
I'd stick with the TL074
The HA4741 is a 3.5MHz chip with 1.6V/us slew so its no quad 741.
The TL074 would not really be an improvement

I've replaced the 4741s with the TL074s, they do sound cleaner, but a bit thin on the low end.
