Daedalon EG-01 Checkout
This Daedalon EG-01 was made to be used in educational settings. The unit is no longer produced or supported; I had no documentation for it. I cleaned the internal PCB and replaced a POT, and then struggled with replacing the knob, of all things! A quick check on the scope showed both sine and triangle outputs working well, with good overlap between the multiplier ranges.
Follow-up!
Shortly after I posted the first video a YT user sent me the instruction manual, with schematic (stamped 1988)! With this in hand, I was able to more accurately adjust the output frequency ranges. A copy is available here:
