ECH200 Triode, Heptode Tungsram Vacuum Electronic Tube

This is an original, Tungsram ECH200 Triode, Heptode, decal electronic tube. The triode and heptode are completely separated within the glass envelope because of the available one extra, added pin. The ECH200 decal tube is designed for RF [Radio Frequency] but useable in AF [Audio Frequency] circuits. A heptode or a triode is useful for many other special purpose circuits like oscillators, RF amplifiers, multivibrators, blocking oscillator, replacement part, circuit research and experimentation or for antique radio, instrument, TV television restoration projects or to set up a private vacuum tube museum. It is NOS tube - New Old Stock, unused, without box, excellent condition.
