donating a schematic to the public domain?

[Phil_S]

Many of us acquire donor amps (like old PA's) and then we find out there's no easy (or free) way to obtain a schematic. Often times we intend to strip the amp. Nevertheless, schematics can contain a wealth of information on things like voltages, resistor ratings in Watts, transformer specs and wire assignments, odd ball parts, etc.

I finally got the bottom plate for the Dukane 1F460 I'm going to be stripping down and it has the schematic. I'd like to do what I think is a good deed, place an image in the public domain. (I don't imagine an out of production 1964 amp schematic is a problem with respect to copyright.) How and where can I do this effectively.

Because it is stuck to the bottom plate, I can't get it to lay flat on the scanner glass (out of focus PDF results), but I now have a decent photo (jpg) that I'd like share. In particular, there seems to be a dearth of information on Dukane PA's on the internet.

Any advice? Or feel free...here it is.

Call the file exactly what it is and make it public.

Lots of old schematix are copyright-owned by Sams Photofact. And copyright is now life plus 70 years? In spite of all this, tons of schematix find their way to free on-line access.

Thanks very much. These are all great suggestions, but frustrating, too!
Schematic Heaven: email returned as not deliverable
FIS: upload error
EL34 World: appears to be limited to guitar amps only
Keep 'em coming. One might stick!
