I'm no longer selling the unmatched ones, now I only offer the matched ones (quad/octet).
I matched them within 0.05mA, guaranteed no more than 0.1mA (10V/25°C).
Price as follows :
$13 (quad) & $24 (octet) for Idss 6 mA range (only few sets left)
$16 (quad) & $30 (octet) for Idss 7-8 mA range
$20 (quad) & $38 (octet) for Idss 9-10 mA range (only few sets left)
Shipping by Registered Mail would be flat @$10 (Worldwide).
The last photo was taken from an old Sansui board, just to prove that the JFET with the marking like the one I'm selling used to exist.
Guarantee these are genuine Toshiba, If not, just send them back to me (I'll cover the returning cost) and get your money back.
PM me if interested
Thanks

Received them within a week across the pacific, packed very well and measures well, too!
Thank you so much!
Thank you so much!
You're Welcome -Xu,
Glad to hear you are satisfied.
Nice report btw, really appreciate that
I just wanted to post some test results of the 2SK170's I purchased from this listing in case anyone was considering them.
I took 10 random samples from 100 total units. Using Erno Borberly's test circuit shown on the bottom right of the first image I tested for IDSS and Vp (VGS).
At +10 vdc and -10vdc I got:
(Sample # ) -Vp / IDSS mA
(1) .477 / 7.05
(2) .564 / 8.85
(3) .543 / 9.15
(4) .511 / 8.23
(5) .514 / 7.80
(6) .458 / 7.07
(7) .453 / 7.04
(8) .493 / 8.43
(9) .517 / 9.10
(10) .515 / 8.25
It looks like they are all within spec.
