Vacuum tube equivalents

- equivalents for thermionic valve or vacuum tube substitution or replacement including the diode, triode, tetrode, pentode, heptode, etc ...

Vacuum Tube / Thermionic Valves Includes:
Basics     How does a tube work     Vacuum tube electrodes     Diode valve / tube     Triode     Tetrode     Beam Tetrode     Pentode     Equivalents     Pin connections     Numbering systems     Valve sockets / bases     Travelling wave tube    

With the very large number of vacuum tubes or thermionic valves that were produced and as a result of the multiple vacuum tube numbering systems that were in use, there are generally equivalents for most types of tube.

In most cases the tubes manufactured to the European system have an exact equivalent tube in the American system and vice versa. These equivalents are very useful when replacements or substitutions are required.
