Biased diode in feedback circuit prevents regeneration.Feedback cannot occur until negative-going pulse greater then bias appears at plate of secondary-emission pentode. Diode bias varies sensitivity, allowing use as pulse-height discriminator also.-E. J. Martin, Jr., How to Use the Secondary-Emission Pentacle, Electronics, 33:41, p 60-63.
