Default About replacing the NJM-4559 by LM4562 in this circuit

Hello

I would modified a Onkyo receiver.

I want to replace the NJM-4559 of the phono and tone control, it is Q301 and Q351 on the schematic I included.

Btw, the NJM-4559 are quite noisy in the phono section, it's a very bad op-amp anyway.

I was think of LM4562 op-amps, but is it not a bit more unstable than the NJM-4559 ?

Does the LM4562 op-amp would work good in that schematic ?

After that I will change all the power amp section.

Thank

Bye

Gaetan
