I'm having a terrible time trying to successfully match a resistor to a JFET for my microphone project (U87 clone). Anyone sell matching fet and resistor sets?
 
Well, the best is, you know somebody with a signal generator and a scope.
Maybe someone in your area can help you.

Does that thing work for setting R value? I saw that and was wondering. Thanks!

The  Peak Atlas DCA75 measure hfe of transistors and JFETS and has curve tracing capabilities when connected via USB cable to a computer, so it's a great tool for semiconductors matching.

I don't know what you mean by "it working to set R value"

 
Biasing of single FETs in mic applications is done to minimize distortion and maximize output. As FETs vary, it needs to be done for each individual FET in each individual mic.
