The Kawai & Teisco Analog Synths Group

--- Yasou Christos, I repair synths on the side and I just got a SX-
210 tha a customer brought in  in pieces. What I noticed about these 
boards is that if the buttons were pushed hard because of dirty 
contacts, they had a tendancy to lift the solder pad. You might want 
to look very close at the solder pads. I had to repair 6 of the 
switch solder pads
