Mine is not grounded. If I ground the ring on the digital out it will work fine, if not digital won't lock.

Okay... so this is going way beyond the shallow bounds of my memory... but I seem to remember there being a run of machines that somehow didn't have the digital output grounded, which caused clicking and popping when it was used. I don't think this affected the analog outputs, though... but maybe something to check. If I remember correctly, the digital output could easily be grounded to the chassis without having to open it up, or there was a way to connect the ground on the PCB with trace pencil. Good luck!

No I don't have the service manual unfortunately. According to EPR Electronics it is/was only available to authorized service centers.
