    • An ultralinear final triode electrode system for a low-frequency amplifier comprises anode (A), cathode (K), grid (G), heating (F), fastening (1-4, 9, 10) and cooling (5-8) elements. The system is arranged in such a way that the distances from the surface of the cathode (K) to the grid (G) and to the anode (A) are constant for all emission places of the cathode (K). The cathode (K) consists of very thin directly heated cathode plates or tapes of 10 to 40 mu m thickness, their planes defined by width and length being oriented in a direction parallel with the corresponding planes of the other electrodes (A, G); the cathode (K) comprises cathode plates or tapes of nickel, their main sides being provided with an emission active material (E), whereas edges and flanks of the cathode tapes are free of the active material (E).
    • 用于低频放大器的超小型最终三极管电极系统包括阳极(A),阴极(K),栅格(G),加热(F),紧固(1-4,9,10)和冷却(5-8) 元素。 该系统被布置成使得从阴极(K)的表面到栅格(G)和阳极(A)的距离对于阴极(K)的所有发射位置是恒定的。 阴极(K)由非常薄的直接加热的阴极板或10至40μm厚的带组成,它们的平面由宽度和长度限定,其方向与其他电极(A,G)的相应平面平行; 阴极(K)包括阴极板或镍带,它们的主边设有发射活性材料(E),而阴极带的边缘和侧面没有活性材料(E)。
