This is an area that is dominated by commercial information resellers. One outstanding exception is Nostalgia Air, which has a growing data base of radio schematics. Some of the links here point to Nostalgia Air's database, but if you can't find it here, check with them.
There is some overlap with Ham Radio and Consumer Audio equipment, so check those categories also.
