Welcome to tubeprojects.com

 

Vacuum tubes were the technology from the 1920s through the early 1970's until the "solid state" era took over.  Try one of our 1950's style tube projects, and re-live the satisfaction of building a working electronic device using vacuum tubes.

 

At the left is an open view of the regulated B+ supply getting a checkout as it nears completion.

Come back to the fifties!

 

The projects featured here are for tekkies of all ages who like the warm glow of vacuum tubes and appreciate the skills it takes to turn out a working piece of tube gear. All projects have been designed, constructed, and debugged prior to offering them on the web site to insure a successful outcome.  

 

A complete document package is available at a small charge for each project with schematics, layouts, phopts, and the theory of operation in a fifties-style magazine format.

Also, check out the new Collins 30L1 interface and switched 2.5 dB RF pad used with Yaesu radios in the Products tab. No more accessing the menus and resetting the radio power!
