Vacuum Tube Circuits

Last update: 24.3.01

You are looking for vacuum tube circuits? So perhaps you will find here what you are looking for.
But remember that this site is just starting up so in some months there will be more stuff here.

For hifi-amplifier-circuits have also a look at the datasheet-site. There are some examples too.

If you have any questions or comment or cool circuits then e-mail me!
