Looking for Soundtracs RX-8 manual or schematics

Hi fellow elektronauts,

I got a Soundtracs RX-8 mixer that needs some love, but I can’t find a manual or schematics of the mixer anywhere on the webs. Anyone that has it and is willing to help me out?


Any info is also appreciated! Any (past) users here? There’s zero to none info out there except from an old SOS review.

No one?
