Apologies if this is the wrong thread, but tech_association in California is selling quads of 'USA Stock Toshiba 2SK170 LAB Tested Quad 4 matched N FETs 7-10mA' for $19 here: https://www.ebay.com/itm/256263712435
And LME49710HA mono opamps for $3.99 here: https://www.ebay.com/itm/256652413375 I'm more interested in these but there a lot of Chinese fakes around.
They have plenty of positive reviews, some confirming genuine parts, no complaints. What do you think?

I can vouch for tech_association, I have bought more than 100 jfets from him and curve traced a large sample, they are legit parts, and the matched pairs, quads and octets are well matched.
There are sometimes 2SK170BL and 2SJ74BL available in the diyAudio store so I would check there too.
