Tungsol KT150 - KT150

The KT150 is a totally new design intended for high end audio use. The Tung-Sol KT150 is the most powerful octal beam tetrode ever produced. It has a plate dissipation of 70 watts and so a pair of KT150s can allow an amplifier with a power output approaching 280 watts to be built.

After the introduction of the highly successful Tung-Sol KT120, Russias premier vacuum tube inventors set to work to develop an even more powerful audio output valve.

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.

The market reaction to this valve has been overwhelming, the praise that this valve has received leaves me in not bought this will be used in designs of the future. Comments have ranged from the huge dynamic power and depth of the soundstage. The bass is fast and tight with a warm and neutral midrange. The top end is both transparent with excellent clarity.
