From LTwiki-Wiki for LTspice

I am a tube amplifier designer and use LT-SPICE to design the circuit.LT-SPICE is really a good software to help me to simulate the circuit that I designed, with simulation I can easily find the problem of the circuit. I like music and HiFi equipment. And I live in china now, many frinds of mine used this software a lot in different way, they like it a lot.
