That's my Pa !
What Da Ya Mean? Papa finally adopted ZM !!!
So to get a similar amp with 5W output only needs 500 ish jfets total. This comes in at under £200 - cheap as chips
We could also use a transformer before one of the driving cell to reverse its phase so that we could use only 2sk170s a'la F6
This looks like a crazy build. Would love to make something similar.
I have a few questions.
Would this work with an unbalanced source?
Is there just 1 single 1K resistor feeding all of the JFETs, or does each cell have one each?
Are there alternative JFETs that could be used which are cheaper and more available?

That's a shame. So there arn't cheaper JFETs with a similar spec available?
There are still suitable parts out there, mostly switches with high
transconductance and high Idss. You might have to degenerate them more
with higher Source resistances, but it's do-able.
I have a few rolls of Fairchild J112's and P1086's that I'm certain would work,
and you can be sure there are others.
