JP's List of Original General Radio Manuals

This is the list of original manuals I have on hand. They are generally NOT for sale, though I'm always open to trading!

Also note that you can get almost any GR manual on a CD from The General Radio Historical Society or directly from Henry Hall at .

I've scanned some of my manuals at high resolution. If there's something on this list that you need, send me mail, and I'll scan and post it as time allows. Many thanks to Jerry Ingordo (KC2HAE) for scanning several of the manuals on this list! The manuals scans are on a friend's webserver, at the end of a cable modem, so these files will take several minutes to download--please be patient!
