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....
