Discussion about the Korg PolySix synthesizer

Yesterday i changed IC28 and IC 31 - as far as i can see these have to do
with octave switch and waveform select (D00-D03) - and they still dont work
(along with pwm etc).


If i follow the signal chain my next guess would be that either IC32
(TC5514APL3) or IC33 (1408) is broken since they are the only ones that
have to do with the broken parameters, and they are the only ones that are
"after" what i have repaired in the signal chain.


-What would be good substitues for IC32 (TC5514) - IC 33 (1408) and IC 33
(14042)?

Thanks again everyone!
