Dear All,
this is my first thread here. I am Bob and it is long time ago since I made my elecronic degree.
Today I wished the my brain would remember better.
I have a Max038 in my Function Generator which is bad.
The signal come in @ BHout. It is a sinus, square, triangle with a level of
1Vpp. It runs in the gate of the (Q107, Q108) 2SK117. The source level is 14V DC. The drain level is zero.
How can I test a FET is the attached circuit. I assume it is a differential amp. But it is not clear to me how it works.
By the way the unit is a Victor VC2002. i can post all the data sheets if needed.
Best regards
bob
Is is a J-FET is N type.
