Hi.
I forgot to day that I'm hoping to find a method where the mosfet's
can stay in the tube, that's why I thought about the hot kanthal wire
method. I have to experiment a little with that. It's also easier that
way to ge the right lenght, since the components themself will be the
reference...
Or maybe it's easier to just sell them in lots of 50 (or whatever
makes up a full tube...) :-)

:-)

This isn't [AD], but since you asked politely... :-)

At least the following types (and aprox quantities) :

IRF540, N-chan 100V / 28A (a couple of 100s)
IRF9640, P-chan -200V / -11A (a couple of 100s)
IRFB9N60A, N-chan 600V / 9.2A (aprox 550)
Intersil 75643P, N-chan 100V / 75A (aprox 21.000)
IXYS IXFX55N50, N-chan 500V / 55A (Digikey: $23.80/ea. Aprox 1.100)

All TO220 (IXYS : "Plus247")
Data codes normaly 01 or 02.

If there is any interest from the piclist members, I might
come up with a "list-price", so to speak. Or simply make
me an offer (amount from 1 and up). Data codes normaly 01-02.

Now over to cutting the tubes... :-)

Jan-Erik.
