CES Ed-Lab 900 - vintage modular banana plug interface unit.
I believe this is from the 1970s or 80s.
These units were used for educational purposes to teach electronic patching via a vast interface panel with loads of banana plug insert points. In recent years apparently these have been integrated into modular synth systems and have been used as the basis of crazy circuit bent instruments. Such projects are beyond me so I offer this to somebody with the skills to see it through.
The unit is in good condition with minor USE wear and blemishes. It has a number engraved on the face and some scratches. A couple of the switch shafts are bent but intact. There is a push button cap missing but the button itself is intact. It comes with the case and a bag full of banana plug cables.
IT HAS NOT BEEN TESTED IN ANY WAY AND IS SOLD STRICTLY AS-IS.
I also have a CES Ed-Lab 700 model for sale under a separate listing.
