6AS6 is a type of vacuum tubes made by the US company, Sylvania. It is an analog amplifier with dual diode-triode configuration. It has a high amplification factor up to 250. It can be used as a preamplifier and power amplifier in audio and radio applications. Its high voltage input and low voltage output makes it ideal for low-level signal amplification. The maximum plate dissipation of 6AS6 is 3 watts and the operating temperature range is -55C to +125C, making it suitable for a wide range of applications. The tube has a small size, making it easy to install in a variety of environments. The 6AS6 also has gold plated and nickel-plated sockets for better contact and durability.
