I have the complete manufacturer's documentation. It's for a 5B505 model, I think there variations. The console I had looked just like yours. I've scanned the sheets at 600 dpi, which made for some large files. They're a bit odd as the pamphlet was a folded sheet thing, page 3 continues on page 10, some schematics are split between 2 sheets, etc. If i still have the software for the old flatbed scanner, I could set it up some day, blah, blah. The files are too large to upload here. PM me with your email and I should be able to send them.
