Yamaha CS80

Steve,

At least then you don't have almost endless boards and sockets to deal with (CS80 can be quite daunting, especially the top side circuits)

The CS50/60 does not have that many CMOS when compared with the CS80 (no polyphonic aftertouch). Also, there is already decoupling on the boards (The 0.1uf ceramics) and i would not use the sockets with the capacitors unless needed. 

Here are the correct Mill-Max sockets and digikey part numbers and manufacturer part numbers.

IC SOCKET 16POS .300" DIP GOLD	ED3316-ND	110-93-316-41-001000	Mil-Max
IC SOCKET 14POS .300" DIP GOLD	ED3314-ND	110-93-314-41-001000	Mil-Max
IC SOCKET 8POS .300" DIP GOLD	ED3308-ND	110-93-308-41-001000	Mil-Max


To my knowledge it is not possible to add more voices. I have not attempted nor will i in the future.

Andrew
