Hi, i don't know if this is off topic here.

I had this keyboard for more than 20 years, it had some keys not working and several other issues. Now i decided to repair it.

cleaning the contacts on the keys and repairing some broken connectors cured almost everything, but still i have problems with the rythms. the keyboard is entirely analog. Cymbals and snares only made a "tac" sound. I already found the problem on the cymbals. i was the transistor on the white noise generator installed backwards, but the snares are still not working.

Anyone knows where i can fin the schematic for this?
