Kawai S-100F: First check up of basic functions

I recently purchased a new friend for the Synthcave: The Kawai Synthesizer 100F. This gem was born around 1980 and for many synthesists it is an instrument they would never give away because of its unique sound. Basically my device is in a good overall condition but it desperately needs a service. Many faders don't work as they should and I'm not sure if I want to know what I'm going to find when I open it up 😳 In this video I'm checking some basic features and try to figure out how the signal flow works. ======================== Check out my S-100F cleaning/servicing video:    • [Kawai S-100F] 40 yo japanese beauty gets ...
