The European equivalent for the 2N3639 / 2N3640 is
BSX36
I've been through all "Vergleichstabellen" etc. Alas, the BSX36 is also
unobtanium.
If it's of any help I do have about 10pcs 2N3639
(NOS) in stock.
I'll try the Baker clamp first, but I need to order a batch of BAT46,
first. I'll also order a couple of BS250 just to test the MOSFET idea.
