Thread: Help troubleshooting a JFET circuit.

Could you post a photo of the original problem so we could see if somehow
you are interpreting it differently than we would?

I just tried the physical circuit (I used a J310 because I don't have a
2N4860 and J310 seems very similar) and I can't get anything like the
voltages they describe by making any one resistor open or shorted,
regardless of whether I use a 10Mohm input impedance voltmeter or a 10G ohm
impedance voltmeter. If I open the source resistor and measure Vs, I get
about 3V with either the Rin=10Mohm meter or the Rin=10Gohm meter.
