Do you have any GR grade 2SK170?

Microchip via RS Components make depletion mode mosfets.
I found the 2sk170 to have a low DS max voltage so used Microchip devices instead.
Although, you have to beware Microchip pin out is opposite to 2sk170.

That's very interesting.

Which Microchip Jfet did you use instead of the 2SK170? Do they have a replacement for the 2SJ74 too?

Depending on the application, the noise from the MOSFet can be objectionable.
