Power Triode (Graphite Anode)

The PL833C is a tri-electrode tube designed for use as a modulator, amplifier, and oscillator. The exclusivePenta Laboratories graphite-anode construction enables the PL833C to dissipate a full 550 watts,exceeding industry standards by some 20 percent. At maximum ratings, the tube is cooled by forced air flowover the seals and envelop. The PL833C utilizes a thoriated tungsten filament.
