I am intrigued enough by the Berning ZOTL amp to actually try and build one. But before I do a working LTSpice model to understand the design was an necessity for me. So I created a model that matches his patent. I am sure there is many stuff left out of the patent that is important but discovering those in a simulation beats finding out on the bench. So this first attempt is an idealized model, switches instead of FETs, idealized transformers, but a real tube model (6NJ6 screen driven). So being totally new to ZOTL and screen drive this may be an interesting journey. The model does work (I think).
Next steps is to optimize ideal model then bit by bit put in real components....

Update: I built out the model a little more with a 6N1P phase-splitter and mosfet drive for the 6AV5 screens. Still mostly idealized with a few real components sneaking in. Simulating decent performance so far, now trying to get more power out. Simming to 6W before distortion. Should be able to get at least 20W out of a PP 6AV5.
