CV2188 travelling wave amplifier
This is a travelling wave tube. It carries the internal markings LZN 11.J.W.
(a): The first anode draws negligible current and may be supplied by a potentiometer connected between the helix supply and cathode.
(b): The optimum helix voltage for individual valves lies between 2.8 and 3.2kV
(c): Between 3dB power points
(d): With collector current of 14mA and helix voltage within ±20V of the optimum value
(e): for small signal levels; At maximum output it is approx 4dB lower.
