mm5824n for Korg PS series

[riccardo]

Hi all,
any place you know where I can get these ICs for the Korg PS 3100/3200/3300
series?

BTW  I always heard the PS 3300 has 3 oscillator per note. I think it does
not, it has six  signal generators boards,  coupled to provide 12 generator
(one for each note in an octave) whose frequencies are then
divided/multiplied to provide the complete frequency ranges and polyphony.
Anybody can clear this point?

ciao
