572B Vintage Svetlana Triode Transmitting Tube (NOS/NIB)

572B Vintage Svetlana Triode Transmitting Tube (NOS/NIB)

• Only to be used in vertical position 

The Svetlana 572B is a high-mu power triode intended for use in Class AB, Class B and Class C, RF and audio amplifiers. This tube features a low-loss white ceramic base and a bonded white ceramic plate cap thermal insulator for high power RF transmitting capability. The emperature-initiated titanium “getter” material is permanently embedded in the surface of the rugged graphite anode for superior gas absorption. This improved “getter” system operates continuously at high temperature, and is more than six times effective than flash getters, silvered on the tube's glass envelope.

The 572B may be used as a direct drop-in replacement in linear amplifiers using the 811A. Reliability will be enhanced by the upgraded overload capability of this rugged graphite plate tube.

High-quality fabrication and vacuum processing at high temperature enables Svetlana to manufacture the 572B with consistent performance and extended life.
