Tung-Sol KT150 Quad Matched 4 Set

Purchased from an authorized dealer - 30 hours or so on them, but I don't have a tube amp anymore, so selling! I have 2 listings for these, both quad matced, but if you need 8, buy both listings as they are matched as a set of 8.

The overall sound of the KT150 is thunderously powerful. The bass is tight, full, and precise with a neutral midrange and transparent high end clarity. The dynamics are unlike anything we have ever heard before. This is truly the Tyrannosaurus Rex of beam tetrodes.

What the manufacturer says: "With the new KT150, Tung-Sol continues to lead in the audio power tube, power game. After the introduction of the highly successful Tung-Sol KT120, Russia's premier vacuum tube inventor, Valery Krivtsov, in collaboration with Irusha Bitukova and a team of ExpoPUL tube designers, set to work in our laboratories to develop an even more powerful audio output tube.

With a massive plate dissipation of 70 watts, the Tung-Sol KT150 is the most powerful octal beam tetrode ever produced. 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.
