    Hi All;

    I live in Australia and also new to this forum. I'm seriously interested in getting a copy of an Electronics Circuit Analysis Program for drawing Vacuum Tube circuits ( Audio Amplifiers ). It does not have to be the latest edition, but as I am unemployed I cannot afford the luxury of a $5,000 dollar program such as Microcap 9 ( by Spectrum software ) or similar.

    I am running Windows XP ( 256MB RAM, 2.4 Ghz Processor & 80Gb HDD) on my computer, so an older program should suffice. If you can help, please email me at my address below.

    Thanks & Cheers;

    There are several websites offering SPICE models of many tubes. Use the search terms "spice model" and "vacuum tube" with your favorite search engine.

    Loosewire, how would such a manual help with simulation or software-based analysis?
