    Hi I am working on a Marantz SD8000, I was wondering if anybody can describe the symptoms when the optocouplers fail?

    Marantz SD 9000 Compudeck Problem

    Hello. I trying to fix my SD8000 Compudeck, did the Optocoupler replacement but when I switch it on only the Clock/Counter display blinks and when I load a tape the flywheel turns and nothing else happens. No Play/FF etc. How do I know if I have the right type of Couplers. Any thoughts?? Thanks.
