Hi all! I came across a very interestingly looking triode
from the 800-family: 842
*Moderate Ra @ 2.5k
*12W dissipation (or more if someone wants steroid KR tube version)
..anyone has a Spice model? The usual suspect Stephie ?
Thanks!

I find that when I do some very complex simulations, the matrix math seems to get complex enough internally to cause those kind of problems. It gets particularly frustrating when you're using LT built in op amps and whatnot.
Sometimes using GEAR analysis will relieve the problem. Also, try the .noopiter Spice directive.
I usually try all the devices once I've added them to make sure I didn't mess up somewhere when I entered the data.
At some point (yeah, my bucket list just keeps getting longer) I intend to take the models to a new level. With the current "simple" tube models, there are a lot of compromises as you simply can't model the "edges" very well. I feel that LTs built in BV and BI behavioural sources ought to be able to help, since they are really powerful.
