Circuit Overview:
     These are the original Yamaha FM synthesis effort, packaged in a piano type case. I think I still know a guy who wants to sell one if anyone is looking to get one of these beasts. More of a museum piece now because of size and relatively crude hardware of course. Nice feeling keyboard of course and some classic sounds. Some site apparently had schemos up at one time. No more though that I can find.


Service Tips:
     Anyone?


Parts:
While Yamaha normally does not keep parts around more than 5 years or so, some older ones can be gotten from NTS Pro Audio. Otherwise try your local Yamaha dealer or Service person.
