Thank you so much! It will take me some time to sort out your work - but if I get that working I will start a new thread.
My JFet tester is pictured below. I cannot figure out how to get the readings I need. I do not see anything wrong with the way it is made compared to the non-IC version posted. One thing i have tried is just powering up the tester and using my + probe on the Source & Gate and I can get readings that look like they could be close - but I am not sure.
By the way - I hate to admit it but I have already blown up 3 J201s (over a few days) because I keep getting confused about the pinout. I check it, but my mind has problems with the "mirror image" effect where I try to see something "backwards" and for some reason I still get it wrong.
Funny - the only time I got a reading that looked like a real J201 Idss (in the 600 range) it turned out I had it backwards - kaplow. So, I turned the next one right side around and the readings are in the 200 range - so, I don't know if its me or the JFets - probably me.
Yeah, I was so thrilled to be getting the 5457s thinking they would be better than J201s, and they aren't. Now I have had to order more J201s.
BTW, I also thought the trimmer seemed to low for the THOR J201. But the squeal, trebly sound is unreal. It sounds like an out of phase Fender Squire through a radio shack transistor radio.
FYI: there is nothing between black & red wires on the switch (just looks like it), and the LED/CLR is on its own, just there to tell me its on. The S & G are each linked to the other S & G, 9v goes to the drain.
