ELECTRON's Links Page



The links listed below are extra special to vacuum tube (valve) enthusiasts.

I believe they provide an important contribution to vacuum tube technology that is worth preserving.

They are very useful for their comprehensive, special, complete, rare or uniqueinformation, explanation of tube design, application and use.

Have a look at them yourself and make up your own mind.

If you are aware of any other important contributions to thermionic tube theory, application or use, email me details and I will include them in this page if suitable.

Please note that if the link you select does not work it is because its owner has changed or deleted the site.
