Kryna Tube Radiator - Extra Large Tube Cooler.



Fitting for: 6550, KT88, KT66, 845, 300B etc.

Inner Diameter up to approximately 45mm



When KRYNA’s TubeRadiator is wrapped around a vacuum tube, it dissipates the heat accumulated in the tube to the outside. This new type of tube cooler is made of bronze containing phosphorus that is excellent in spring characteristics and strength. The corrugated form adheres to vacuum tube and demonstrates high radiating effect.



By increasing the radiating effect the temperature of the surface of vacuum tube decreases, resulting in less thermal noise and a clearer sound. Lowering the temperature of the vacuum tube's surface also increases the life expectancy of the tube



Test results of measured plate vibration in a tube indicates the effect of controlling low-frequency vibrations related to high-order harmonic and the power supply. Furthermore, bronze containing phosphorus has a characteristic of absorbing electromagnetic wave. Therefore, this tube cooler also plays a role of filtering noise as it prevents the external impact on the tube.
