Hi,
I have SL4000 E console from 1986 with almost complete original documentation.
What I would need most is a part of section 1 of Service Manual, particularly pages from 1-19 to 1-24. These are channel amps (transformer and transformer-less) with schematics and connectors descriptions.
I would love to complete all the documentation.
Of course I'm ready to share if any of you need anything. (TurboScan app does great job with large format schematics)
