The GU48/833A is a power triode intended for use in RF amplifier, oscillator, or class B modulator service.

The GU48/833A features rugged construction for high power RF transmitter applications.

The envelope is fabricated from hard glass intended specifically for the high-temperature operation of transmitting tubes.

The internal tube parts are supported by low loss ceramic insulators for high-temperature operation and high voltage hold-off.

The rugged grid structure is particularly well suited for industrial heating appliciations.

It can also be used for audio amplification :   Wavac SH-833 $50k:   also for Tesla coil :

These tubes are still being sought after today over 65 years after their introduction.

833A is Legendary American Tube!
