Tried multiple amps, multiple power outlets in the house, multiple power supplies, multiple guitars. The shrill tone is always there when density is left of noon. This is when the pedal is bypassed (off).
Hi folks. I built a Deflector and noticed that even if its bypassed it puts out a high pitched tone which is audible through the amp. This seems to be occurring when the density knob is left of 12 oclock and it is much less noticeable turned right of 12 oclock. Has anyone had this problem? My...
Update: the FNIRSI LCR-P1 tester totally allows measurement of a jfet already attached to a daughterboard. You use the three clips which conveniently hook onto the d/s/g eyelets. I popped two 500 IDSS jfets into the desolate fuzz and it worked like a champ.
Ok your inclusion of sockets in addition to having pin headers makes sense given that you were going to swap the jfets. That's the first mention I've seen of that for jfets. I've definitely socketed for germanium transistors with those little green circle sockets. Is socketing for jfet swaps common?
oh this is something i hadn’t considered. So are you are saying that you put pin header sockets on the pcb (male side through pcb, female side facing up towards the enclosure cover), then put the male/male pin headers through the jfet daughter board, and finally you put the daughterboard...
This graphic is stellar. And that pink is really pleasing. Nice work! That stomp switch breakout board which includes the led is a great addition. Allows the artwork to be uninterrupted. When you use that breakout board what do you do to the solder holes for the led on the main pcb? From the...
Thanks for clarifying. I assume that it doesn’t matter which side of the pin header goes to pcb and which goes to the jfet daughter board? Mine are slightly longer on one side.
Yeah that's what I was thinking. I however don't have the right angle pin headers. I have the straight pin headers. But I think that difference shouldn't matter since those pins can then just sit on a tester like the one I mentioned. Thanks for sharing.
Hi Folks. I've got a few Fairfield Circuitry inspired builds (Chop Shop, Nein) almost done and it's time to get into measuring the JFET's. Coming from a non-engineering background I've pored over any videos on Youtube that remotely mention measuring JFET, IDSS, or both. Many mention measuring...
