The Sylvania 12AU7 is a dual triode vacuum tube widely used in audio preamplifiers, guitar amps, and hi-fi equipment for its smooth, warm tonal character and low noise. With medium gain (mu ≈ 17–20), it’s ideal for line-level amplification, phase inverters, and driver stages. Sylvania’s U.S.-made 12AU7s are respected for their rugged construction, consistent performance, and long life, making them a popular choice among audiophiles, musicians, and vintage gear enthusiasts.
