A 2sj109 is almost impossible to find these days. You can buy 2 matched 2sj74 and use them. A 2sj109 is more or less made of 2 2sj74 in the same chip. There is information on the forums where to buy them from trusted sources and how to install them on the boards.
Is this really the best advice you can give?

diyaudio store has the lsj parts but not matched.
You can buy them matched at fetaudio and also on ebay. there is a recomended seller which has genuine parts.
As I said, searching around the forums will give you alot of answers.
And as many have stated before me, the 2sk170 and 2sj74, were some of the lowest noise transistors available and while there are currently available parts with similar specs they are a compromise in one way or another.
You were looking at the wrong offer. Here is the link for 4 pcs (2 matched pairs) of LSJ74 Grade B, comparable to 2SJ74 Grade BL :

My little town here. Just trying my luck. My town here there are few shops over 40 years old. Just trying my luck. Need to know what I'm looking before I walk in.
