Description
Product Overview
The Acxico 5K 5W single‑ended audio transformer is engineered specifically for high‑fidelity tube amplifier systems. Its core is built from high‑grade silicon steel sheets that provide stable magnetic performance while minimizing core losses. The windings use oxygen‑free copper, a material chosen for its superior conductivity and resistance to oxidation, ensuring long‑term reliability even under continuous operation.
Designed with a compact footprint of 1.97 x 2.36 x 2.17 inches and weighing just 0.6 kilograms, this transformer fits easily into tight chassis layouts without sacrificing performance. The fully lacquered iron shell offers complete electromagnetic shielding, reducing hum and interference for a cleaner audio signal. The mounting hole center distance of 70 mm aligns with standard chassis designs, simplifying installation for both hobbyists and professional technicians.
Key specifications include a primary impedance of 5 KΩ and a secondary range of 0‑4 Ω to 8 Ω, making it versatile for a variety of tube amp configurations. The winding method follows a 3+2 fever grade pattern, delivering consistent inductance and low distortion across the audio spectrum. With UL certification, the transformer meets rigorous safety and performance standards, providing peace of mind for users who demand quality.
Usage
This transformer excels in both DIY audio projects and professional studio environments. Whether you are building a boutique tube pre‑amp, restoring a vintage amplifier, or integrating a new high‑end audio system, the Acxico 5K 5W transformer delivers the isolation and low‑noise performance required for pristine sound reproduction.
Its robust construction makes it suitable for touring rigs and live‑sound applications where durability and consistent performance are critical. The transformer’s compact size allows it to be mounted in confined spaces, such as rack‑mount chassis or custom wooden enclosures, without compromising airflow or heat dissipation.
For audiophiles seeking to upgrade existing equipment, the transformer can be retrofitted into legacy designs, providing modern shielding and efficiency while preserving the classic tonal character of tube amplification. Its universal mounting pattern and standard dimensions ensure compatibility with a wide range of amplifier models.

FAQ
What is the recommended mounting method for this transformer?
The transformer is designed for a standard 70 mm hole center spacing. You can secure it using screws or brackets that match the mounting holes on the chassis. Ensure the surrounding area is free of conductive debris to maintain optimal shielding performance.
Can this transformer be used with both Class A and Class AB tube amplifiers?
Yes, the 5 KΩ primary impedance and flexible secondary range (0‑4 Ω to 8 Ω) make it suitable for a variety of tube amplifier classes, including Class A and Class AB designs. Adjust the secondary load to match your specific tube configuration for best results.
How does the fully lacquered iron shell improve audio quality?
The lacquered iron shell acts as a Faraday cage, blocking external electromagnetic interference that can introduce hum or hiss into the audio signal. This shielding results in a cleaner, more accurate sound reproduction, especially in environments with high electrical noise.
What warranty does Acxico provide for this transformer?
Acxico offers a one‑year limited warranty covering manufacturing defects and material failures. If you encounter any issues, contact our support team with the product serial number, and we will arrange a replacement or repair as appropriate.
Is this transformer compatible with European voltage standards?
The transformer itself is voltage‑agnostic, as it operates on the audio signal level rather than mains power. It can be safely used in any region, provided the surrounding circuitry is designed for the local voltage specifications.
