Every CS-80 that I've repaired with aftertouch problems needed some of
the chips on the TKC board, TSB1 board, and/or TSB2 board replaced. I
usually just replace them all. They're listed as boards 3, 4 and 5 on my
chip list:

When replacing the TKC chips, use decoupled, turned-pin sockets (Mil-Max
or equivalent).
