The 6SN7 is a type of vacuum tube, also known as a thermionic valve, that was commonly used in electronics during the mid-20th century. It was typically used as an amplifier or frequency converter in radios, televisions, and other electronic equipment. The 6SN7 is a double triode tube, meaning it has two independent amplification stages within a single envelope. It is easily recognizable by its cylindrical shape and distinctive metal base.
