tube software

Hi,

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.

Cheers,

Rada
