This 572B High-mu power triode is manufactured by Shuguang in China. Great quality 572-B for use in Class AB2, Class B, Class C RF, and audio amplifiers.
Due to datasheets that do not list the same conditions as Western made 572B tubes, we are uncertain if the Shuguang 572B has the same maximum ratings as USA made tubes.
