Anyone know what the optos used in the "super" series were? They're not marked in the schemo and these things are a huge PITA to get the pcb out of. Got a bad one in the clean section that works ok for a while then all hell breaks loose....passes distorted signal and tons of crackley noise when it shouldn't. This is with the vol full down. OD ch works fine. These are a bit goofy looking as the resistive side is center tapped.
