KT88 / 6550

Single tube, not matched

With a massive plate dissipation of 70 watts, the Tung-Sol KT150 is the most powerful octal beam tetrode ever produced. A pair of KT150s can allow an amplifier with a power output approaching 300 watts to be built.

The Tung-Sol KT150 glass envelope is a special egg shaped balloon that was developed to improve thermal dissipation and maintain a superior vacuum for the best sound. The fact that the glass envelope has no flat sides means the Tung-Sol KT150 has no problems with microphonics.

2 tubes, matched as pair

The Tung-Sol KT170 was developed due to the success and popularity of the KT120 and KT150 tubes, aiming to provide even higher power capability. As the largest and most powerful tube in its series, it features an 85-watt power dissipation, allowing amplifiers to reach over 300 watts, and an original-shaped glass bulb designed for high vacuum and heat dissipation at high power levels.
