( Brand: One Electron ), ( Model: JAN CRC OA3 7655 ), ( Type: Vacuum Tube )
The OA3 7655 is a high-quality electron tube, specifically designed for use in audio applications. This vacuum tube is a triode, which means it has three elements: a cathode, a grid, and a plate. The OA3 7655 triode tube is known for its excellent frequency response, making it a popular choice for use in audio amplifiers, particularly in the high-frequency range.
The OA3 7655 tube is made with high-quality materials, including a tungsten filament and a glass envelope. The filament is heated to a high temperature to generate the electrons that flow through the tube, while the glass envelope provides a protective barrier to keep the vacuum inside. The tube's elements are carefully aligned and vacuum-sealed to ensure optimal performance.
The OA3 7655 tube has a plate resistance of 2000 ohms and a plate capacitance of 120 pF. It also has a maximum plate voltage of 400V and a maximum plate current of 100mA. These specifications make it suitable for use in a range of audio applications, including power amplifiers, preamplifiers, and even some types of radio transmitters.
The sound quality produced by the OA3 7655 tube is widely regarded as being warm and rich, with a smooth and detailed frequency response. It has a natural sound that is often preferred over the more clinical sound produced by solid-state electronics. The tube also has a low noise floor, which means it can reproduce even the smallest details in the audio signal.
In summary, the OA3 7655 is a high-quality electron tube that is well-suited for use in audio applications. Its excellent frequency response, warm and rich sound quality, and low noise floor make it a popular choice for audio enthusiasts and professionals alike. It is a reliable and durable component that can be expected to provide many years of reliable service in a wide range of audio applications.
