Valve amplifiers at anode current decreasing: Principle of operation

Published 16.07.2010 Presenter Anton Pankratov

In vacuum-tube amplifiers I created, I used the usual high-voltage lamps with anode low voltage. However, after the anode current was reduced, the slope of the tube characteristics changed, and its amplification dropped. But there are ways of feeding tubes with low anode voltage, which worsen their parameters to a lesser degree ...
