The upper input terminal goes to the grid, pin 1, of a pentode tube. The grid goes to ground through a resistor labeled R sub c. The lower input terminal is grounded. The cathode, pin 7, goes to ground through a resistor labeled R sub k. The suppressor grid, pin 2, is tied to the cathode. The screen grid, pin 6, goes through a capacitor labeled C sub C2 to the cathode. The screen also goes through a resistor labeled R sub c2 to E sub bb. The plate, pin 5, goes through a resistor labeled R sub b to E sub bb. The plate also goes through a capacitor labeled C sub C to the upper output terminal. The upper output terminal also goes through a resistor labeled R sub cf to ground. The lower output terminal is grounded. End verbal description.
