  1. Now, this is one awesome tube! I know, I know, it’s a new production tubes, but a lot of them have surprised me in a good way. This tube is a beauty! The egg shape definitely makes this tube one of the best looking tubes out there – and they, we buy tube amps not only because they sound great, but they look superb! This tube make a tube amp look very futuristing (this is not good for every amp though).

    Sound is as expected – this tube has balls! Bass produced is absolutely superb – tight and precise – no mushiness here. Mid-range is on a dry side, but still quite good – the tubes haven’t been burned in completely yet, so we will see if it improves. On the top of that, overall transparency and top end extension is very impressive. One of the best sound stages that I’ve heard from a power tube. All in all a very impressive tube – now we need amplifiers that are specifically designed for it. Right now amplifiers have been designed to except the tube, but not take full advantage of the tube’s potential.

    Characteristics of the tubes – here

    A word from New Sensor:
    “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. 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.

    The manufacturers who are developing amplifiers to use this tube have reported that the Tung-Sol KT150 sounds great in all power amplifier configurations including single-ended, triode connected and ultra-linear. The tone signature of the Tung-Sol KT150 is characterized by a strong bass signature with balance and clarity throughout the audio frequency spectrum.”
