Roland Saturn SA-09 ..need help & schematics

Post by crafter57 » Thu Jul 02, 2020 2:06 am

Hi everyone, I'm in need of the Roland SA-09 schematics, not RS-09.. they seem similar but not the same.
I spent 1.5 days troubleshooting with those but realized some traces span across 2-3 circuits boards, its a crazy layout and hard to get in there with test eqmt. Also, very hard to find parts on the circuits boards as nothing, no components are numbered or silkscreened.
Anyhow, The problem I'm having is the "Organ" setting is not working, I removed the switch and qualified it as well as the connections and the transistors.
Any help or information greatly appreciated.
thanks
