I don't know how I inspired you in any way, but you do beautiful work. Thanks for the post, and I will be sending for the schematic, just to satisfy my curiosity.
I am wondering how to apply a minimal amount of NFB around the output stage of a circlotron, just to reduce output Z down to a level acceptable for driving my Sound Lab speakers. Goal is to get the output Z down to 1 or 2 ohms from 6 or 7 ohms.
