Hi,

does anybody know about a russian chip called KP1012ИK2 ? :-)

   http://dl.dropbox.com/u/6263674/_temp/formanta-ems-01-pcb.jpg

I'm repairing a Formanta EMS-01
(Russian two-manual stringmachine/Polivoks-ish-synth,
http://www.ruskeys.net/eng/base/formanta.php )
and suspect that I've encountered a struggling octave divider IC.
Spares for sale anywhere? Any advice could be helpful.
