I have a quantity of Toshiba 2SK370BL low noise, high transconductance N-channel JFETs and am offering them via AMB audio shop.
These JFETs have identical specifications to the 2SK170, except the plastic casing shape is different, with slightly lower power dissipation. The pin-out is the same as 2SK170, and the power dissipation is usually irrelevant in low signal applications such as the input stage of a pre-amp, power amp or headphone amp. Thus they can be used as direct substitutes for the 2SK170. Note that I have the BL grade devices only (Idss between 6mA and 12mA).
These 2SK370s are being offered as "cut tape", and are not matched for Idss. If you need matched devices, then buy a handful and try your luck at matching yourself.
