I have a schematic, for a turntable mixer, that uses the following NJM/JRC
opamps...
4558
2043
and 4556
specs are at- http://www.njr.com/products/ic/opamps.htm

With all the talk of discontinued ICs, I ask if I should find
generic equivalents for these chips,  or if a better (cleaner) chip
exists?  Should I build it as it is described, as the chips are available
from mouser, or should I switch?

The schematics will be posted in a week :)

Thanks a lot!
