• WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
    Building, troubleshooting and testing of these amplifiers should only be
    performed by someone who is thoroughly familiar with
    the safety precautions around high voltages.

tube software


If you are looking for a software to draw loadlines and estimate operating points, there was a thread not so long ago with title "beta testers wanted" that tube software seemed interesting.

If you use Matlab and are relatively familiar with it, I have a Matlab based software to design SE triode amps that I can share.
