Hi,
this far all my tube work has been manual bias point calculations by hand and this has provided such accurate results I've never needed LTspice. I've used LTspice for opamp and PSU work and become quite fond of the software. Results are trustworthy and very accurately translate to real world it seems.
I've read reports it could also create useful ballpark figures or sometimes even perfectly accurate predictions for real world tube designs. But then I've also read the quality of the tube models vary a whole lot, much more than transistors and opamps directly from the manufacturers. They seem to vary so much in fact I've shied away from starting any tube design in LTspice.
Please share experiences. And please post or link to tube models or whole collections you know to be accurate, trustworthy or at least useful for general design decisions.
I'm a member of the yahoo ltspice group and found plenty of models there, but their sources and accuracy is often questionable.
