TUBE_BUILD

Post by sbench »

The Spice file below (tube_build.asc) is intended to allow you to more easily create a Spice model for a triode. You can adjust the tube parameters in the model, and run the simulation to see if they correctly model your device. The adjust parameters are a superset of the Koren and the Java Script parameters. The examplt file is set up for an 833, and it pretty well models that device in both A1 and A2 as well as grid current.

The Spice file also lets you tailor the maximum voltages, step sizes etc, as well as maximum currents. Thus, you don't have to manually re-scale things.

The Spice file is intended to be self documenting. I have also given an indication of what the different parameters do. I have also included directions as text how to add your newly created tube into the triode_nh.txt file.

Incidentally, using the behavioural sources for the display allows auto scaling pretty easily, and that makes it easy to set up the parameters just like the "data sheet" is set up.

Enjoy,
Stephie <3
