| Please note that in the near future, the material on this page will be migrated to my newest and greatest project yet, Tubeopedia , an online compendium of electron tube related knowledge that almost anyone can edit! Please bookmark the new page. To save bandwidth and unnecessary duplication, I am going to basically limit this space to homebrew DIY tube projects and other odd stuff we have that you're unlikely to see elsewhere. Links to sites with a plethora of schematics for older tube amplifiers, ham equipment & radios, and homebrew projects are listed to the right below. All schematics on my site are in Adode Acrobat PDF format. If you have diagrams, links, articles or schematics you think would be appropriate for this page, please contact me for details on how submit them. |
