Vacuum Tube - 6AN8A, Triode, Pentode
New-Old-Stock (NOS) tube.
The 6AN8A is a medium mu triode and a sharp cutoff pentode in the 9 pin miniature construction. The pentode section may be used as an IF amplifier or a reactance tube while the triode section is well suited for use in low-frequency-oscillator, sync clipper, sync separator, and phase splitter circuits. Thermal characteristics of the heater are controlled such that heater voltage surges during the warm-up cycle are minimized provided it is used with other types which are similarly controlled.
