Hi Martin,
Thanks for the advice.
I have some low noise audio FETs (2SK170 etc) that I got a long time ago.
I thought could not use them for RF because of large Ciss.?
However, LTSPICE simulation to show that NFB can be effective.
besides VLF is close to AF, so I will try it.
?
tnx & 73, Hisami 7L4IOU
