The schematic uses standard symbols. Using the jfet's data sheet, and searching the internet will provide you with the info you need. I put little stickers on mine to make sure I wouldn't mix them up.
After some reading from the suggestion, I think this is how i suppose to connect the JFet chip.
the middle leg or GATE goes to the 1uf cap.
the DRAIN leg goes to 10k resistor, 18V supply, etc...
the SOURCE leg goes to the 10uf cap
Thanks again everyone for your help.

Did you check a datasheet for the jfets you have? i think some of the sk170 have different pinouts
The Jfets that i have are the ones that I've ordered from Pass DIY that came with the board. I had mine working with the included board. Nice i was able to make it to work well, I now want to remove the JFets off the board and experience with making it point to point.
according to the datasheets the pinout of the Tosh and Linear are identical. Linear describe their lsk as a replacement for the Tosh 2sk
It's the other jFETs that come in various pin outs.
I have been thinking about building a BoZ on the output cap which is a large poly about 1" long and 3/4" tall.
You could probably do the same with the B1. My BoZSE has no input caps and you would have to relocate the large storage caps or replace them with one 100uf cap or something.

I thought they were only made (lincensed by in any way) by Toshiba. We know that they are reaching their End Of Life but, what about the other manufacturers, are they still producing?
Are they really equivalent replacements or just have some thins in common and it's just a commercial approach?

I thought they were no longer being manufactured, but mouser.com lists the Toshiba 2sk170 as a new item.
Quick question guys,
in stead of metalfilm resistors, can i use carbonfilm-resistors?
(not sure if "carbonfilm" is the correct name, could it be "coal"? i have to translate from Dutch, sorry)
I rather not use digikey-BOM because of 30 dollars shipping on 8 dollar items.
thanks

hhmmm..here goes another pre-Xmax-B1-components-related Q?😉
Can i change the standard Digikey-BOM panasonic C1 and C2 elco
with this one form pana?
it's 10.000μF, which shouldnt be a problem (>1000μF should be okay in B1) but will it fit? Slightly confused about mounting, snap-in, throughhole etcetera.
Pin-diameter is the same @ 0.8mm (sorry, metric-dude here) and distance @ 10mm. Size wouldnt be a problem 25mm x 35mm (wxh) as Digikey-elco is 22x50 mm's.
i gladly welcome all advices and alternatives
Merry Xmas* from the Netherlands
*i know....almost...almost...just practising already 😉

It's 1/3 smaller than the value specified. Try to find a 15000uf. You may use a bigger voltage rating - 35v.
