Review NATIONAL UNION Triodes Twin Vacuum Tubes

The E1148 Triodes National 2C22 Union Twin Vacuum Tubes are a pair of high-quality, vintage-style tubes that are sure to add a unique touch to any audio system. These tubes are manufactured by Union Electronics, a well-respected name in the vacuum tube industry, and are based on the National 2C22 design.

The E1148 Triodes are pentode tubes, which means they have five active elements. This design provides a wide range of applications, from audio amplification to oscillation and rectification. The tubes have a plate heater filament voltage of 6.3V and a filament current of 0.25A, making them easy to integrate into most audio systems.

The glass envelopes of the E1148 Triodes are made of high-quality borosilicate glass, which is known for its strength and resistance to thermal shock. The tubes have a heater filament made of tungsten, which provides a long lifespan and reliable operation. The tubes also have a metal grid, which helps to control the flow of electrons and improves the overall performance of the tube.

The E1148 Triodes are designed to deliver a warm, rich sound with a good balance of bass, midrange, and treble. They have a high power handling capability, making them suitable for use in power amplifiers. The tubes also have a low noise level, which helps to ensure clear and distortion-free sound.

In terms of physical dimensions, the E1148 Triodes have a diameter of 9.52mm and a height of 141.4mm. They are designed to fit standard EIA 7-pin sockets, making them easy to install in most audio systems.

Overall, the E1148 Triodes National 2C22 Union Twin Vacuum Tubes are a great choice for anyone looking to add a vintage touch to their audio system while also enjoying high-quality sound. Their robust construction, high power handling capability, and low noise level make them a reliable and long-lasting addition to any audio setup.
