Midget Broadcast Set with 955 acorn tube
Georg Richter

A nice instruction how to build a midget broadcast set with the 955 acorn tube was issued in the book "Radio For The Millions" (prepared in 1945 by Popular Science Monthly staff, but first published in "Popular Scienece Monthly" November 1938).

Enjoy the attachment.

Best Regards
