Review TELEFUNKEN 2post 10.4 Vintage Tube Siemens Mhos Sonotone Audio

This is a high-quality vacuum tube, specifically a 12AU7/ECC82/ECC82S, manufactured by Siemens. This tube is a 2-pin, 11.4mA, 10.4V, and 2450 microhenry (mH) unit, making it ideal for use in a variety of audio applications.

The tube is of the 12AU7/ECC82 family, which is widely used in preamplifier stages, equalizers, and other audio applications due to its excellent signal-to-noise ratio and low distortion. This particular tube was manufactured in 1975, making it a vintage unit that may add a unique sound character to your audio equipment.

Notably, this tube is a 12AU7 equivalent, which is a common replacement for Telefunken and Sonotone 12AX7 tubes. It is also often used as a replacement for the 12AT7, 12AV7, and 12AY7 tubes. The 2-pin design of this tube makes it easy to install in most audio equipment, and its 10.4V operating voltage is a standard for many vintage audio devices.

The 2450 microhenry (mH) output transformer tapping is a feature that allows you to fine-tune the tube's output characteristics to better suit your specific audio application. This feature is particularly useful in circuits that require a specific output impedance or voltage.

Overall, this Siemens 12AU7/ECC82/ECC82S tube is a high-quality, vintage unit that can add warmth and character to your audio equipment. Its 2-pin design, 10.4V operating voltage, and 2450mH output transformer tapping make it a versatile and reliable choice for audio applications.
