I have been using the trial for a few days, and I must say it's fairly user friendly. I like that the most popular tubes are already in the database. I should have a pretty good grasp of it by the end of the trial period. I may just go ahead and take the plunge. I really need something like this to get a grasp on what's really going on in the tube world!! I know it doesn't replace real world prototyping, but its a start.

Would thoroughly enjoy any input.

I haven't looked at B2 SPICE ("Beige Bag SPICE") in a decade or two, though at one time I considered purchasing it. For pure circuit simulation I don't think you can beat the no-charge LTSpice (see http://www.linear.com/designtools/software/ ). Be sure to join the unofficial User's Group at http://tech.groups.yahoo.com/group/LTspice/ where you can get pretty much all the help you'll reasonably need. (Start by studying the organization of the "Files" section.)

There are many examples of vacuum tube circuit simulations in the Group's "Messages", and comments about making them run. Go to "Files > Tables of Contents" at < http://tech.groups.yahoo.com/group/LTspice/files/ Tables of Contents/ > and use your browser's "Find" function to search for "tube" in the "all_files.htm" master index of Group resources at < http://f1.grp.yahoofs.com/v1/jCitUi..._ovVFOva6A/ Tables of Contents/all_files.htm >.

The "Tubes_Valves" directory in "Files > Lib > Tubes_Valves" at < http://tech.groups.yahoo.com/group/LTspice/files/ Lib/Tubes_Valves/ > includes libraries containing models for dozens of tube types.

Even if you stay with B2 SPICE the tube model files may be useful to you.

I'll look into that. It's something to consider.

I sat down and learned the free LTSpice about a year ago and have not looked back. I've found all the tube models I ever needed, just a google away.

I don't bother with that free power supply program anymore PSUD, I just LTSPICE it!

I use B2Spice at work.
When it came to upgrade our Microcap Spice Simulator and found just how many thousands of dollars they wanted, my Technical Manager instructed me to find something to replace it instead.
B2Spice is what I choose.
I have found them BeigeBag quite helpfull. I had to generate a model for avalanche transistors when designing a Q-Switch driver for a laser. They were responsive to my queries and very helpfull. They also have good tutorials on getting frequency response and distortion plots from amplifier circuit simulations etc.

If you don't need/expect any support then use LTSpice which is free.

Cheers,
Ian
