Abstract :
A description is given of some negative grid triodes of unusual design which operate both as oscillators and as amplifiers at frequencies higher than those previously reported. These tubes differ from the conventional primarily in the number and arrangement of the leads. When used as oscillators the upper frequency limits are increased by this arrangement to approximately 1.3 times the values otherwise obtained. Stable operations are secured as amplifiers at somewhat lower frequencies, the stability outputs and distortion ratios being comparable with those obtained from pentodes of similar ratings.
