    Hi All,

    I dug out my old Portastudio 424 (Original!) to start making some noise/drone/ambient textures. I'm starting with making some continuous loop cassettes. I'm having some success. I got a little demo video and how to at the link below, if you're interested...

    Moving forward, I'd like to do some modifications to my 424 to enable some non-traditional uses of the device. For example, I'd like to add a switch to disable the erase head. I'd also like to setup some internal electronic loopback to enable some audio feedback without have to use external cables. All of these mods would be much easier if I had a schematic (or the service manual). Does anyone have the schematics for the original 424?

    Thanks,

    Chip
