FET VOLTMETER


Posted on Feb 4, 2014

This FETVM replaces the function of the VTVM while at the same time ridding the in-strument of the usual line cord. In addition, drift rates are far superior to vacuum tube circuits allowing a 0. 5 volt full scale range which is impractical with most vacuum tubes. The low-leakage, low-noise 2N4340 is an ideal device for this application.
