Abstract:

Design of the final version of the half size nuvistor designated as the developmental typeA15274 was completed. A few initial samples of this tube were completed. Heater power input was fixed at 400 milliwatts and a 700 mc noise figure of 7.5 db is attainable at 400 milliwatts plate power input. Practical difficulties in grid fabrication delayed fabrication of sufficient ube samples for more complete electrical and mechanical testing. Author
