# Where can I find a five-tube electric radio design from the 1920s?

A specific five-tube all-electric receiver design from a period electronics magazine, with source issue and starting page in the unlock.

What the unlock delivers: **the exact original article, issue, printed page number, and preserved source location**. This is a historical reference locator—not a newly tested technique, downloadable kit, or claim of exclusive rights to the source.
