Model: RK7577

Special Features:

Envelope material: metal; mfg class: amplitron; reference data, v-7403, instruction book, arsr-1d/e/f, vol 5, pg 10-735; v-7403, instruction book, arsr-2, vol 5, pg 10-540

Properties:

An inclosure, including two or more electrodes, in which a flow of electrons may occur through a vacuum or a contained gas. The electronic conduction takes place either by means of electrons emitted from a cathode or by ionization of the contained gas. Includes phototubes (photoemissive type only), geiger-mueller tubes, traveling wave tubes, cathode ray tubes and microwave tubes (klystron, magnetron, or the like). Excludes items whose primary purpose is to produce light energy. Also excludes photoelectric cell; and semiconductor device (as modified).
