6AU5GT Sylvania – Beam Tetrode for Audio and Sweep Circuits
Durable and Musical Output Tube for Amplifiers and Vintage TVs

The 6AU5GT Sylvania is a beam power tetrode designed for output stages in both audio amplifiers and vintage television sweep circuits. Its rugged construction and efficient design make it a top choice for those restoring or upgrading classic gear. Whether driving a speaker or generating vertical deflection, the 6AU5GT offers powerful performance with dependable results.

This tube uses an octal base and features a compact glass envelope, making it compatible with a wide range of mid-century audio and television equipment. In audio circuits, it excels at delivering clear, harmonically rich sound, especially when used in single-ended or push-pull output stages. Additionally, it works well with common preamp and driver tubes like the 6SN7 or 12AX7, helping achieve a smooth, detailed sonic profile.

In CRT televisions, the 6AU5GT Sylvania provides reliable vertical deflection current, contributing to a stable and consistent image. Because it can handle high voltages and thermal stress, it’s an excellent replacement for worn-out sweep tubes in vintage sets. Its beam-forming plates reduce screen grid current, improving efficiency and longevity compared to traditional pentodes.

This tube stands out for its blend of power, efficiency, and tone. While its maximum output isn’t as high as larger beam tetrodes, it delivers beautifully rounded sound in lower-wattage amplifiers—perfect for hi-fi setups, guitar amps, and mono console restorations.

Choose the 6AU5GT Sylvania when authenticity, clarity, and durability matter. Its reliable output, smooth response, and compatibility with classic designs make it a trusted option for technicians, audiophiles, and vintage electronics enthusiasts.
