Vacuum Tube - 6072-A, Triode, Dual
New-Old-Stock (NOS) tube.
The 6072A is a low-noise, low-microphonic miniature twin triode designed primarily for use in the low-level stages of high-gain audio-frequency amplifiers.
The 6072-A is a special quality tube intended for use in critical industrial and military applications in which operational dependability is of primary importance. Features of the tube include a high degree of mechanical strength and a heater-cathode construction capable of withstanding many thousand cycles of intermittent operation. When used in on-off control applications, the tube will maintain its emission capabilities after long periods of operation under cutoff conditions.
