WTB 2SJ44 N (NEC P-Jfet)

This one is done.

Wanted to say thanks to everyone who pitched in with info or a helpful link. I was able to get 20 genuine pieces of J44 for a good price. Plenty to play around with.

so, did you actually try anything interesting with the complementary pairs for all that trouble?
🙂

I can’t say ‘interesting’, but I tried in different buffer arrangements and the FE of an amp. I really like them. They seem like good substitutes for 170/74, at least to my ears. I haven’t been able to make any apples to apples measurements yet, but it’s on my list.

They are better complementary pair than 2SK170/2SJ74.
See the curve tracing I did 14 years ago :

You are very lucky to get just the J44 alone.
Obviously the seller didn't know what he had.

Thanks for sharing that! Also liked the 5R source trick referenced in the doc.
