Hello,
I can always order a FET for you with my next Mouser order, and
stuff it in an untracked letter.

Frank,
Thanks, I could buy those but the truth is that in my
country we have to pay more than 100% taxes. One single FET
would cost more than a whole minimum wage of salary around
here. So I try to avoid importing as much as possible, but it
is a possibility if I don't?find a more widely available part.
Thank you for pointing me to that ad.
Vladan,
That's really valuable info. Where did you get that from?
I've been googling for days and found nothing. I have been
looking at a NS 2N3958 datasheet and am wondering if that
would do the job. Gfs is at least double the minimum you
listed, and Ciss is typically around 3.5pF, but the rest seems
ok. Considering these are select parts, what exactly?did HP
select them for? I'm asking because you seem to have much more
information?than I ever managed to find after many days on
google.?
This
is a selected part, which means that something similar was
widely available, but I can't give you any commercial part
numbers. Here is what I have:
National Semiconductor SF83025 or Intersil ITS31087. These are
custom numbers, don't bother looking for them in old catalogs.
However, see if you can find something similar to the specs
below in NS and Intersil books.:
BVgss 40V min
IDss?? 0.5mA min, 5mA max.
Gfs? 0.5mS min.
Vp/Vgs (threshold)? 0.5V min, 4V max
Ciss? 2pF
Vgs match? 10mV
300mW max
These are almost certainly made with two die per package.
