Yes, but for the standard version, you only need 1 pair of JFETs for CEN, as you can see in the photos.

Zen -> Cen -> Sen, evolution of a minimalistic IV Converter

Also you can read from the article why you need 2 pairs for SEN.
So for the standard kit, you get Dual JFET heatsinks for CEN, and type 10 for SEN.

Jeremy,

> seems like win win

I have answered your request in the GB thread.
Please only post in one place as it is impossible for me to flip back and forth.
And other might get confused in the process.


Thanks,
Patrick

Is this typical for utsource? Some days ago I ordered some 2SK369-V from them

If I am not wrong Ampslab has 2SK369V ??
I have not bought anything from them, I have to admit.

Hi Patrick,

Ampslab and Zhou both have BLs.

Not the V grade, although we could choose high BLs maybe, what Idss should we aim for ?

...Not sure, but the 2SJ74BLs i got from them as well as 2SK2013/2SJ313 were all fakes, '74s had IDSS in the 20+ mA range and the others were fakes as well...there is a thread here somewhere with pictures of those.



I'm sure they have some good stuff but there " unobtanium" ones you have to be doubly careful, test as soon as you get them , they will take them back if you prove they are fakes but don't wait too long.

OK, Ampslab has 2SK372V, which is essnetially the same as 2SK369V but in a different package.
So you need a different (custom) heatsink which does not exist, as yet.

I'll see whether I can find 2SK369V somewhere .....

As discussed in article, min 8mA.
PS I just sent off an enquiry for 200 pcs 2SK369V. See what happens ...
