Fitting for: EL34, 6V6, 5AR4 etc. Inner Diameter up to approximately 35mm.
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.
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
