Source follower replacement for 6C4 w/300V supply

[Helmholtz]

I was referring to RG’s suggestion to feed signal back from the source and boot strapping it.

So did I.
What I'm saying is that the gate circuit impedance is essentially determined by the signal source impedance (around 100k) and the bootstrapping will not make much difference to that.
It's like 100k in parallel with 1M compared to 100k in parallel with 100M.

No sh*t? IM going to think about that a bit to make sense of it.
good stuff, Helm. You should be training ai bots.
