Vacuum Tube Amplifier Circuit Diagram. This is my first successful vacuum tube project. One of the problems with building vacuum tube circuits in the 21st century is that sockets for these components can be difficult to find.

If you are down with bode plots and circuit diagrams though it could serve as a nice introduction to building a class ab amplifier circuit. The output of this small amplifier in which a 6v6gt output pentode is connected as triode is about 4 5 watts. See more ideas about vacuum tube tube valve amplifier.

The simplest vacuum tube the diode contains only two elements.

The slides are pretty heavy on engineering design terms but give a good feel for what it takes to construct and tune an audio amplifier using vacuum tube technology. Current can only flow in one direction through the device between the two electrodes as electrons emitted by the hot cathode.
