Thanks for the assistance. As it turns out, my particular installation of LTSpice will not use the NH5751 definition in dmtriodep.inc. The gain for even this corrected circuit is still around 0.0008. A member of the Yahoo LTSpice group provided a different model that was accurate enough for me to ge...

For some fershlugginer reason I will never comprehend, I cannot read a *private* message until I have make 5 posts, so here is the fourth of 4 posts to meet the requirement. Let's see if I can make a post only 1 minute after the previous one. Nope... let's see if 1:30 or thereabouts is enough. Jeff

While the ultimate goal is to simulate a differential cascode amplifier circuit, I tried starting with a simple Class A tube amp. However, the simulation isn't working (the gain is either zero, or negligibly far from zero). Would someone please look at the attached file and tell me what I am doing w...
