I came across this discussion while researching my EH-8000, which i purchased many years ago from the guitarist in the Vancouver noise band Tunnel Canary. Although I don’t think i want to sell this unit, I do think I’d like to get it up and running again, as it made quite a wonderful racket and I’m getting back into analog synthesis after a 20-year absence.

Would anyone be able to point me in the direction of schematics and/or a tech who’d be willing to take this on?
