Power - Triode ·Triode
Power triode for audio-output, amplifier, or oscillator service with manufacturer operating data supporting substantial power delivery.
this tube type because of several specific advantages over metals such as tantalum, molybdenum, and nickel. The radiating area of graphite is approximately twice the projected anode area be- cause of its surface porosity and it will dissipate at least four times more heat than metal.
