I built a Sabbra Cadabra using J201s and a 2N4401. While it sounds really good as is, I was wondering if the proper JFETs and BJT would make that much of a difference. I read through the thread in the main page and on FSB and there didn’t seem to be much discussion about whether they worked better or not. Is it work buying a set of 4393s or is going to be negligible in the end? Thanks.
I’m not sure what difference it will make, I bought a bag of the 4393 (Siliconix/Vishay) because at the time they were cheap.
I have subbed them for J201 in several circuits when I didn’t feel like soldering up the smd J201 things. That has worked fine for me, so maybe it’s pretty similar to J201. I haven’t tested any of their specs though
