[Kawai S-100F] 40 yo japanese beauty gets intense cleanup & service

In this video I show how I cleaned and serviced the Kawai Synthesizer-100F. The 100F is a mono synth from the late 70s. It has one oscillator with sawtooth and square waveform, white noise (that can't be mixed), two envelopes and a LFO speeding up to audio rate, a lowpass and a highpass filter. The lowpass filter can be modulated by LFO, envelope and waveforms that gives pretty unique sound design possibilities. The unit was very dirty when I purchased it. Almost all faders were banged, resonance didn't work at all. I decided to give it a deep clean-up and a fresh calibration. I didn't want to do a makeover but rather bring back the vintage beauty of this wonderful synth without removing all of its patina. Background music was made usind the 100F among the Vermona Synthesizer, Yamaha CS-5, Waldorf Streichfett, Behringer Deepmind, Model D & Neutron and Elektron Model:Samples.
