Anyone else have one? For those unfamiliar, the Fun Machine is a cheesey home organ/piano that was manufactured in the 1970s. I recently picked on up for 50 bucks, and I love it. I'm just curious if anyone else has one, has modified one, or has a circuit diagram for one. What I really want to do with mine is disconnect the keyboard from the internal amplifier and run it through my bass rig. At the very least, I'd like to make a line out that I could run into my amp. My fun machine is the 121F model, without the headphone output, so I couldn't just modify that. I'm fixing to just open the thing up and to see what it looks like though.
