It might be one-phase Blowtorch or non-balanced Blowtorch, or half-Blowtorch, but it's still push-pull, not single-ended...Ah, a single-ended Blowtorch with JFETs. 😉....
No matter how many inarticulate sources you quote, it is still a push-pull design ...
This is a push pull design if there ever was one...
patrick, there is a paper from Nelson pass that explains the single ended concept - it's a great read. I'll dig up the link a little later and post it if I have time. Or else just google and it will pop up.
Of course if by single ended, we meant unbalanced (input/output) then that might explain the confusion.

Of course, it's all clear from the beginning.
It was just a (rather simple) joke: single-ended input vs. single-ended gain stage topology but now I see that it never had a chance... 😱

How important is it to use C-grade (~15 Idss) jfets? The store is always out and I have a whole bunch of B-grade jfets. Would I need to increase R4 and R5?

Am I correct that the original schematic generates an inverted signal at output?
Thanks
Check link in post 4, then presentation link in post 1.
