Could someone please explain to me the difference between these 2 Jfets?
I am currently working on a u87 clone build and I am unsure which one I should use. I understand that the 2sk170 is considered a medium gain fet, but what about the J309? Would the J309 be more similar to a 2n3819 (high gain fet) or the 2sk170 (medium gain fet)?
I'm not getting enough gain out of the 2n3819 so I want to swap it with a different fet and I have both a J309 and 2sk170. I have to max out my mic gain before I can even get a decent mic signal.
Also, would anyone recommend swapping out the 1:8:1 trans for a T13? Dave from Advanced Audio recommended I stick with the stock 1:8:1 but I see a lot of people building u87 clones and using the T13.
