Did you check the audio out board....... .can you make a basic patch
with osc,filter,vca?

If the machine sounds with a basic patch, the tape is bad or
incomplete.. .you should be able to grab the vca knob and raise it to
hear sound....... if you cannot hear the sound of the basic patch, your
audio out board may not be seated or connected.

I think some of those machines had an audio upgrade to stereo and this
could be the culprit.
