LoLi Plot Vacuum Tube Bias

We hope this application helps you design a single ended or class A electronic valve amplifier.

You can select the vacuum tube operating point and check the 2nd. harmonic distortion for one or more load lines and grid swing voltage points.

Also, you can check the power output and the plate power dissipation.

Its operation is very intuitive and you can work in a touch mode and make a value fine adjust with inc/decrement buttons or input edit text.

The main screen has two panels: one panel on the right side, with the plate curves graphic, and the other one on the left side, with a drop down list to select the valve and many text fields with the variable values.
