Thanks for the prompt response, the problem I'm running into is that not only can't I find the J202, but those mentioned replacements generally have a lower voltage rating, for example the J202 has a 40v vds, while the others only 25v. I have thought of placing, for example, a 2N5485, increase the source resistance in order to decrease the vds and, if necessary, increase the value of RNFB in the return circuit to equalize the levels. My only doubt so far is that there will be a change in tone once the modifications have been made, my main idea was to leave the original circuit, but it is impossible to get a J202 around here. I listen to some suggestions. From already thank you very much
