Tung-Sol KT150 Vacuum Tube Features CryoAcoustic Treatment by Music Direct for Better Sound and Longer Life: The Latest in a Legendary Line of Tubes Is Capable of 70 Watts of Plate Dissipation
The massive Tung-Sol KT150 vacuum tube is capable of 70 watts of plate dissipation, enough to drive practically any design with room to spare. Bold, authoritative, and powerful, yet smooth, warm, and delicate when it needs to be, KT150 is the latest tube in one of audio's most famous lineages. In September 1950, Tung-Sol introduced the 5881, an industrial version of the 6L6GA with a 23.5W plate dissipation, opening the doors to the hi-fi movement of the 1950s. This rugged tube also found a home in the '59 Fender Bassman and servo amplifiers used in B-52 bombers. In 1955 Tung-Sol, further raised the bar of high fidelity with the introduction of the 35W 6550, which could deliver 100 watts with a pair in push-pull configuration. This tube was used in the Dynaco Mark III and Sunn amplifers. KT150 comes with CryoAcoustic Treatment by Music Direct.
Music Direct CryoAcoustic Tube Treatment
Tubes have long been renowned for providing unparalleled audio experiences. But did you know you'll hear even better sound and enjoy longer tube life with our cryogenically treated tubes? The improvement is so profound, Music Direct no longer offers any tubes that are not cryogenically treated. We have invested in our own cryogenic machine, allowing us to do our own in-house testing with temperatures and ramp up/ramp down cycles to maximize the effects on the materials. Countless hours of listening tests have confirmed the advantages of CryoAcoustic Treatment.
The cryogenic process involves cooling materials to very low temperatures through the use of liquid nitrogen. Temperatures reach as low as -190 °C, and the process registers a profound impact on the mechanical properties of materials – particularly metals. Used in aerospace technology, medical tooling, musical instrument construction, critical automotive components, high-pressure cutting tools, and performance-critical sporting goods, cryogenics considerably improve the sonic presentation of vacuum tubes, cables, transformers, and other audio-related products – as well as their internal components. Resistance to corrosion, firmer hardening, and added strength are just a few of the scientifically proven effects of cryogenics. And while the sonic benefits cannot currently be scientifically proven, listening tests confirm an increase in acoustic resolution – which is why we call our process CryoAcoustic Treatment.
