The 6BV8 is a double diode triode with each section having a separate cathode. The design use was as a synchronous detector and chrominance amplifier in colour television receivers. It is also suited to the application in sound receivers of FM demodulation and first AF amplifier.
The RCA logo and the three separate valve sections. The triode is on the left. Each diode has a maximum current rating of 23 mA.
