I have these....I'll try them View attachment 831469
You said low Idss ... I don't know the schematic, but maybe you'll have to change Rs value for lower Idss device.

I said same IDSS as thebones in the BOM but there is no harm I seeing what happens with the aforementioned fetsYou said low Idss ... I don't know the schematic, but maybe you'll have to change Rs value for lower Idss device.

Can you post the latest BOM in the first post, please?
Yes, unless someone finds a through hole version that is better?
If you can find 2sk170c then you could manipulate the legs to fit.
Hence my search to experiment but it seems this version wasnt as popular.
As long as gate is the center pin source and drain don't matter on a JFET.
Ah, thanks craig.As long as gate is the center pin source and drain don't matter on a JFET.
Any input on the use of alternatives for the BF861C?

Not really ... getting close to the Idss of the BF861/BF862 is the key.
Yup, I seeNot really ... getting close to the Idss of the BF861/BF862 is the key.
Just curious what the measurement of the pcb is. I have som different enclosures and my head spin on which one to choose
According to an earlier post: 90 x 245mm
(I remembered seeing it in a post and tried a search for this but came up with nothing. So I did a brute force search...'cause I hadn't made a note!)

US based folks, what transformer are you planning to use for the build?
I picked up the Chinese manufactured R-core mentioned earlier in the thread (R26-90); took 5 weeks arrive, but it's here now!
