Application Notes
To change the frequency range it is best to vary the cathode capacitance and leave the cathode resistance fixed in order to maintain approximately equal output voltages. Maximum frequency is obtained with a square wave or sine wave input. Like all counter tubes the anode resistor should be soldered directly adjacent to the socket to minimize anode to cathode capacitance.
