so its rubbish and not F5, and what then ?
or the whole schematic is rubbish and wont work at all ?

output Jfets are overbiased and will go puff , either with current and with voltage

ah, ok, I would use +/-20V
would that help ?
a few missing resistors maybe ?
ofcourse
do you have any possible size in mind ?
I can just as well admit its not for F5, just to make that clear
but I might use it for my bass guitar, maybe

great, thanks 
and it was in the 2. post only, sooorry...I should have noticed
guess I better start reading now 😀

another silly basshead question 😀 is it possible to go high Z (1Mohm) with that one ?
yup
considering that cable capacity influence will not harm your thick wires frequencies
but , there are better things , made exactly for bass guitars

ah, teasing me 😀 thinking of anything specific ?
no, you are absolutely right, there are better things, but wont there always be
but its a spot on match for the requirements I have for my specific input stage 😉
high-Z input with a little gain(6-12db), and running on +/-20V

ah, will have look, thanks
ehh, I take it there are multiple versions
any particular one to look at ?

you'll probably get more bone with simple Jfet BOZ
ah, I see, have that one in my bass preamp file already, from google

but high 0/+ voltage 😱
but you are right
from reading jfet boz thread, it really is tempting for bass input
simpler, and very well documented
and seems Nelson actually found lower distorting with lower voltage, so taking the positive rail of the +/-20V ought to work ok

looks like I managed to find the parts 😀
