Web sites:
There are many web sites dedicated to tube technology. One of the best is by Max Robinson at www.funwithtubes.net . There is a link on this site to join the Fun With Tubes discussion group on Yahoo. Max is the moderator, and is joined by a wide range of experienced techs in running discussions of tube topics. This is an extremely educational, non-commercial group experience, and is highly recommended for serious tube project builders.
