The Sylvania 6021W and 6021 are two identical 42-pin subminiature twin triode vacuum tubes, specifically modeled as 6112 and 6111. These tubes are part of Sylvania's extensive line of high-quality electronic components, renowned for their durability and reliability.
The 6021W/6112 and 6021/6111 are 6.3V heater-filament tubes, designed for use in a wide range of applications, including audio amplifiers, oscillators, and other electronic circuits. Each tube is equipped with two triode sections, which are isolated from each other to reduce interference and ensure optimal performance.
The first triode section in the 6021W/6112 and 6021/6111 is a current-gain amplifier, capable of delivering a high output current and low distortion. This makes it ideal for use in power amplifiers, where it can drive speakers with ease. The second triode section serves as a voltage-gain amplifier, providing a high level of gain with low noise and distortion. This makes it suitable for use in preamplifiers, mixers, and other signal-processing applications.
The 6021W/6112 and 6021/6111 are compact in size, with a diameter of 0.67 inches and a length of 1.06 inches, making them easy to incorporate into small electronic devices. They also have a low power consumption, which helps to reduce heat dissipation and extend the life of the tube.
Overall, the Sylvania 6021W/6112 and 6021/6111 are versatile and reliable vacuum tubes that offer excellent performance in a variety of applications. Whether you're building a vintage audio system or designing a modern electronic device, these tubes are a great choice for delivering high-quality audio and signal processing.
