working at 95% . The bugs left are from the rewiring , i have surely made some mistake on rewiring the 4 tone matrix boards . also need to find some fresher CD4006 .



The hardest part was to learn the schematic . and to lift the synth on the bench cause as you will in the video i am a skinny dude 200lbs is quite a load for me ;) .



the pw width lfo is bogus . Could be a simple return from the tone matrix .

tolex need to be replaced .

wood siding have to go to the piano finish shop . IS IT CHERRY WOOD !!!

miswired tone matrixs . ANd replace the temporary spliced wires .

Some parts still need to be find.

1 gate is not trigging ( wirering ? )



still got more than 50hrs of works.



here is the youtube link.

I am currently working on restoring a SynergyII+ and SynergyI with a microcontroller board, then, if I succeed I will take on the KAS board and a few other things in my CS80 --- it is very overdue for a complete overhaul but I have just been wary of all that wiring! I'll just have to go real slow but your story is really very inspiring.
