Diode is not necessary in input circuit of secondary-emission pentode, since feedback is from dynode to control grid and negative trigger pulse is impressed on cathode. Used in high-speed, short-duration pulse work.-E. J. Martin, Jr., How to Use the Secondary-Emission Pentode, Electronics, 33:41, p 60-63.
