Vacuum Tube - 6CN7, Dual Diode, Triode
New-Old-Stock (NOS) tube.
The 6CN7 is a duplex-diode high-mu triode in which separate cathodes are provided for the diode and triode sections. The triode section of the 6CN7 is electrically identical to the triode section of the 6T8. The tube is primarily intended for service as a combined horizontal phase detector and reactance tube in television receivers. The triode section may also be used in a variety of other applications, such as in sync-separator, sync-amplifier, or audio-amplifier circuits.
