Subject: CS-80 almost working again! (no aftertouch and missing a voice)

Thought I would update the list on my CS-80 work thats been going on. I had help in fixing some of these problems which is great since some of them to me were stumpers.
Here is what has been done:
Power supply rebuilt
Ring Modulator envelope fixed (bad IG00159)
Output hi/low switch rebuilt
constant pitch/loss of pitch controls (bad trace on the BA board)
Funky 3 would not sound (bad transistor on the BA board)
Some things that are left to do and a bit of a mystery:
No aftertouch. (The aftertouch worked when I got the synth but now I have none on any key on either channel which makes me think its something global. The voltages seem to be fine on the TKS board....)
No voice 3 on channel 2, but ONLY in panel mode???? This seems like a weird issue...
And last will be a full calibration.
