Key Features

♦ Smooth and Stable Rectification:
The Primaluna 5AR4 tube is known for its smooth and stable rectification, providing consistent power to the audio amplifier’s circuitry. It ensures that the power supply is stable and efficient, contributing to improved overall sound quality by maintaining steady voltage conversion.

♦ High Voltage Tolerance:
With a peak inverse voltage (PIV) rating of 1,000V, the 5AR4 tube can handle high-voltage conditions without compromising performance. This makes it highly reliable for demanding audio applications, where stable and robust power delivery is critical.

♦ Low Noise Performance:
The Primaluna 5AR4 is specifically designed to operate with minimal noise, which is essential for high-quality audio systems. It delivers a clean, stable signal with minimal distortion or interference, ensuring that the overall sound is as pure and accurate as possible.

♦ Durability and Longevity:
Known for its durability, the 5AR4 tube is designed to offer extended lifespan, providing long-term reliability for audiophiles. The quality materials used in its construction ensure that the tube performs well over time, reducing the need for frequent replacements.

♦ Versatility and Compatibility:
The Primaluna 5AR4 is widely compatible with many high-end tube amplifiers and other audio equipment that require a reliable rectifier. Its versatility makes it a perfect choice for audiophiles looking to upgrade or replace rectifier tubes in their systems, ensuring compatibility with most audio setups.

Primaluna Tubes 5AR4

The Primaluna 5AR4 tube is a high-quality rectifier tube, often used in the power supply section of tube amplifiers and other audio equipment. Its primary role is to convert alternating current (AC) to direct current (DC), which is essential for powering the various components of a tube amplifier. The 5AR4 tube is a well-regarded choice for its smooth rectification characteristics, delivering stable and efficient DC power to the amplifier circuit.

Operating with a heater voltage of 5V and a heater current of 1.9A, the 5AR4 tube is capable of handling significant power demands, while its peak inverse voltage (PIV) of 1,000V makes it highly resilient to voltage surges. This characteristic allows the tube to withstand high-voltage conditions, which is important in tube amplifiers that demand reliable rectification for optimal performance.

Primaluna’s 5AR4 tubes are crafted to ensure low noise and minimal distortion, which is crucial for maintaining the high-fidelity sound expected from high-end audio systems. A stable and low-noise power supply helps preserve the clarity and purity of the audio signal, preventing any unwanted hum or hiss that could interfere with the listening experience.

Additionally, Primaluna ensures that their 5AR4 tubes are tested for durability and longevity, ensuring they perform consistently over long periods. These tubes are built with premium materials to resist wear and tear, making them a solid investment for audiophiles who want reliable performance without frequent replacements.

As with all Primaluna tubes, the 5AR4 is tested for quality and consistency, ensuring that each tube meets the brand’s high standards. Whether used as a replacement for an older rectifier tube or as part of a new amplifier build, the Primaluna 5AR4 ensures a clean, smooth power delivery, essential for achieving the best possible audio performance.
