Vacuum Tube - 12AV6, Diode, Dual Triode
New-Old-Stock (NOS) tube.
The 12AV6 combines a high mu triode and two independent diode units in the 7-pin miniature construction. It permits a single tube to function as detector, AVC rectifier, and audio amplifier. Coupling between the diode and triode sections is minimized by the use of internal shielding.
