Insane

Couldn't figure out non ~AC use for j-Fet ... bullsh¡t -- the DC setup for j-Fet at 5V supply allows it to be used as a 1-st high impedance stage at 4-stg voltage amplifier which is likely frequency dependent thus non-DC amp

so i combined what i had seen in web with what i'd learn so far . . . and we got a nice median of previous post

(whats it worth  ´>.<`)
