MOTM

Radio Shack used to supply schematics in their manuals. I fixed a few
things using that info.

Ham radio gear typically comes with schematics (hams are expected to be
a least a bit technically competent by license).

I've also been sucessful in a lot of cases getting factory service
manuals for VCRs, camcorders, etc. They can cost $20-50 or more.

Actually, the schematics and contents of our manuals are protected (in
theory) by the California Uniform Trade Secrets Act. There is a notice
on the front cover and schematics of all manuals written or updated in
the last two years. By purchasing the product and opening the manual,
the customer assumes a responsibility to make reasonable efforts to
assure the confidentiality of the material.
