JFET Bias tool box

012/5/21

This is a So cool tools for bias the JFET, find the Iss, Pinch-off Voltage, via experimental, not Calculation.  The following circuit used by VE7BPO ,http://www.qrp.pops.net/jfet-bias-2006.asp .  suggest by <<EMRFD>>.

I make it with 3 POT to simple the work, no solder, no change anything, with brilliant Knob, look Cool!
