Have not worked with 2SK170 at high B+ before. For a future singlestage preamp-project I intend to use it with the DC-working point like below with B+=90-100V, Vd=35-38V, Id=8mA, P=280mW. This is quite close to the limits of 40V/10mA.
Will there be any immediate risk of frying it due to the high B+? My main concern is what will happen on "power up".

I have heard of fets being selected at the factory for over 2x their nominal V rating as a special order product
but if you're looking for for low noise you really don't want to push the Vds - look for "hot carrier" noise
maybe you could talk yourself into counting a cascode as "single" stage?

. This is intended to be a line stage so noise will not be that problematic.- Status
