Hi! I needed to fix up a couple of synths, and since these chips are heaps hard to come by, anyone know a replacement circuit.

I have the schematic for the KEIO TS 201012 used in the older Korgs, but I need those 3 to fix up some other older synth.

Can anyone help with these?

I could of swore that I had a schematic for the TS200011 around but all I can find right now is the TS200012. If you happen to find one could you post it or msg it to me? I'll let you know if I have any luck finding it before you do (I could of swore I had a copy somewhere...)

Here's the schematics for the TS200011 and TS200012. They should be easy enough to replicate on a breadboard. You may need to look into transistor substitutions though..
