Description

The PSVANE 274B-AT is a directly heated full-wave rectifier, mirroring the performance of classic tubes like the 5U4G, 5Z4P, and 5Z3P, while also capable of replacing the GZ34 in most applications. It benefits from advanced ceramics and anode technology that minimize conductivity issues and thermal stress, enhancing sound purity and operational stability for a high-quality audio experience. The 274B-AT features the Horizon series' exclusive HPC-T coating and a base made of a new material. The Horizon series features newly developed anode coatings, HPC-T anode coating technology addresses the issues of anode heat dissipation and thermal stress, reducing signal distortion, ensuring stable output, and enhancing sound purity. Under precise voltage and temperature control, each PSVANE vacuum tube must undergo at least 24 hours of burn-in test before leaving the factory, to ensure that every product delivered to you is stable and reliable. The 274B-AT is known for its powerful output and exceptional low-frequency performance, offering a rich and deep sound quality. It presents a warm and full audio experience, showcasing profound musical expressiveness.
