I have had a lot of people ask me, after my talk on Hollow-State Homebrewing at FDIM about where they could find interesting theratron (vacuum tube) circuits to build. So I thought I would pass along some references and links to get people started:
Dave’s Homemade Radio. This guy is a real craftsman and homebrew whiz with tubes. A must visit!
Jeff Duntemann’s Junkbox. Lots of interesting tube homebrewing ideas and circuits + LOTS of info on tube categories.
Electric Radio Magazine. If you are interested in tube gear, homebrewing with tubes, restoring tube equipment, you will definitely want to subscribe to this magazine and get the back issues. It’s been around since the late 1980’s and is edited by Ray Osterwald, N0DMS, who write a lot of the more technical tube articles. They have an index to search for back issue articles. Look for projects by Bob Dennison (SK) and Bruce Vaughn. These guys had many, many great thermatron projects!
If you have any questions on thermatron homebrewing, just let me know.
