Vacuum Tube - 6BV8, Dual Diode, Triode
New-Old-Stock (NOS) tube.
The 6BV8 is a miniature duplex-diode medium-mu triode in which separate cathode and plate connections are provided for each diode section. The tube is intended primarily for service as a combined synchronous detector and chrominance amplifier in color television receivers. The high perveance characteristic of the triode section adapts the tube particularly to this service. It is also suitable for use as a combined FM detector and audio frequency voltage amplifier.
The 6BV8 is especially suited for use where series-connected heaters are employed since it has a 600 milliampere heater current and a controlled heater warm-up characteristics.
