Hello everyone,
I am building a simple phono preamp using Toshiba 2SK117 JFETs and need to know how to measure the IDSS of them so I can match pairs. The best help that Google has given me is the rather vague;
Connect Gate to Source
Connect to 9-15VDC
Measure current
Now the first step I get, but where do they want me to connect the Voltage? Gate/Source or the drain? And across where do I measure the current?
Thank you very much,
Steven Paul
