TS-KT170

The Tung-Sol KT170 is a high-end beam power tetrode vacuum tube designed for use in the output stages of high-fidelity audio equipment. It boasts a significant power dissipation of 85 watts, which allows amplifiers equipped with a pair of these tubes to achieve power output levels exceeding 300 watts. This makes it the most powerful tube in its class, surpassing its predecessors like the KT120 and KT150 in terms of power handling capability.

The Tung-Sol KT170 features an original shape glass bulb designed to maintain a high vacuum and dissipate heat effectively when operated at high power levels. This design not only aids in thermal management but also contributes to the tube's reliability and sound quality. It includes an equipotential cathode for increased reliability and to effectively amplify audio frequencies.

The Tung-Sol KT170 represents a significant milestone in the development of high-performance vacuum tubes. Its exceptional power handling, thermal management, and ultra-linear operation make it an ideal choice for demanding audio applications. As with all Tung-Sol tubes, the KT170 is built with a commitment to quality and reliability, ensuring a lifetime of exceptional performance and tone.
