Those are discontinued Toshiba devices.
Linear Systems has an LSK389 for the N-channel
as a supposedly better replacement but no P-channel
device as of yet. If I recall from another thread for a GB
we did last year, I think there was discussion on the pinout
being somewhat different on the dual device?

luvdunhill did that GB last year.
You may want to try contacting Marc (luvdunhill)

one possibility for (NOS) 2SK389:
here

looks to be GR only, if that matters to you.

for 2SJ109, i wish you best of luck!

yes i know - it is a really big problem with 2sj109... even i have 2 2sk389 at my home - but no 2sj109...
a friend needs both of them and i need only a P pair....

so, 2pieces of 2sk389 and 4 pieces of 2sj109......will be a problem - i will try to contact Marc..thnx...

any other ideas would be also welcome....

I have some in stock.

USD$20 ea + posting.

Brand new and unused of course.

Scroll down the thread Mlloyd posted till where i posted a link to Partco in Finland.
They only have GR's in stock, but charge €5 for a pair of 2SJ109/2SK389-GR

If you need BL's i'd go for J74/K170 single JFETs, a matched pair mounted to a small heatsink is close as good as a monolythic duo.

o.k. - i will go for that option jacco since i have a good source (cheap and close) for k170/j74...

craig - thanks for offer - it is a good one but i decided to go with a 2sk170/2sj74 combo since i can find a good and reliable source of them very close to me....
thanks man!!
