Very interesting!
I recognize the circuit, Circlomanen made something VERY similar a couple of years ago

That is one very interesting (and well written) piece.

Old wine on new bottles, sure, but with enough attention to detail., to allow anybody to keep up.....even me :D

BTW, a pair of the the cascoded LU1014 a al ZV9 will make a simple yet excellent Circlotron Follower.

Anyone wanting to build one of these should do so soon. The 2SJ74 was discontinued at the start of the year. Some of the distributors will have them in stock for another year or so, but after that they will become very difficult to find.

Can a circlotron work in low bias classAB, or classA is a must?

Obliged producing an amplifier like this for myself will be me.:D
