CAD Program for Tubes

[Family_Dog]

Hi All-

I was wondering if anyone knows of a CAD program which is tube compatible, and either free, or at low-cost.

I am not at all artistic, my hand-drawn straight lines are skew, my resistors look like a drunken worm, my caps are reasonable, and coils & transformers are well-nigh impossible for me to draw freehand.

If you want real-time Spice simulation for tube projects, check out:

There are tons of custom made spice models for other tubes available from the web, like from here:

and

I have a few too that I should post some day

The PCB cad package Eagle (from www.cadsoft.de) has a free library of tube symbols available for download on their website.

Hi Nisbeth,

I gather I would just download what I require from their Libraries in the Downloads section and copy it over to the "Models"Folder. Thanks, am doing so now.
