Abstract
A system and method for monitoring the spot-knocking of electron tubes includes individually identifying each tube carrying hanger and each cart which applies a spot-knocking voltage to the tubes. The hangers and tubes sequentially engage a series of anode bus bar segments and the spot-knocking discharges are counted. The counts for each hanger and for each tube are averaged and compared with stored averages to identify faulty tubes, spot-knocking equipment and carts.
