J175 (or 174 / 176) P Channel FETs

[Meowy]

I've been having great success tweaking a BS250 boost (also P Channel) and thought I would give a JFET a  try.  So I found a few J175 P Channel JFETs.

Are there any OD or boost circuits out there that use these?

I don't know of any, but I am curious to know your thoughts on what you have done with the BS250. I have a couple but have never used them for anything.

You've probably seen the "Crackle Not OK" circuit around, which is derived from the SHO. I took that as a starting point, but i am using it with a positive ground since the BS250 is P Channel. I made a few minor component changes and I really like what I get from it - clean boost with an edge at max gain. I am also messing around with cascading them to push even harder.

Polarity aside, the BS250 is a great alternative to the BS170. They sound and feel very similar, and the 250 seems to have somewhat less noise
