  Somewhere I have a 9826 service manual that's pretty complete. I haven't
looked at it in a long time but I know if had schematics and I'm about 95%
sure that it had a detailed parts list as well.  I came across several
service manuals today but I didn't look at them, I just packed them up to
go to Al.

    Well that's finally in the works!
