Trying to measure VDS across this JFET and all I see is zero. Can you not measure the V across it? I can measure across R1 + J1 or across R1 but cannot measure across the 2N5458 by itself. Is there actually 0V and no internal resistance at all? I wouldn't think so but that is what I am seeing. 0.0000VDC across J1 and 5.9949VDC across R1. R1 actually measures 101.9Ω. I am tweaking the V2 power supply to measure exactly -2.00VDC at the Gate.
