As the frequency control of the A-146 is a voltage divider with 3 terminals
it cannot be replaced by a vactrol. That's why this application is not
mentioned on the A-101-9 manual. If you are experienced with electronics you
may disconnect the pcb track coming from the center terminal of the
frequency control potentiometer and insert a vactrol. But you should have
electronic experience to do this modification. And I have to point out that
warranty is lost in this case.
