graymark: AA5 wall poster
Joe Sousa

Fellow Radiophiles,

I bought this very nice poster on ebay recently. The poster shows a schematic of a generic AA5 (All-American-5) AC/DC AM tube radio, and it was originally published by Graymark.

This version of the AA5 was probably the most produced AM tube radio design ever.

I scanned the large 16"x22" poster, and touched up the wear marks. Click the picture to see the full size version and print it in a large piece of paper to hand in your workshop. Or feel free to post this scan on your web site.

Thanks Joe,  Maybe I can study this and help better understand a more difficult schematic on the old Crosley I'm working on.
