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
