I’ve been skimming through the goldmine of projects on the webpage and checking some part availability. My question is about the JRC4558DD op amp. I believe that was the coveted ts-808 chip if I’m not mistaken. I have a JRS2043DD that I removed from a ts-9 years ago. Can this be substituted for the 4558 in the Dwarvin Hammer without any noticeable difference?
