Know before you buy
The EI-Core transformer is a traditional, reliable choice that offers a classic tube sound. The C-Core upgrade provides improved efficiency, better high-frequency extension, and a more refined, transparent sonic presentation.
The EL34 amplifier is versatile and compatible with speakers ranging from 4 to 16 ohms. It performs best with high-efficiency speakers, though its 35W per channel output is sufficient for many mid-80dB sensitivity designs.
The integrated version includes a pre-amplifier section with a 12AU7 buffer board, allowing you to connect sources directly to the amplifier. The power amplifier version omits this stage, requiring a separate pre-amplifier to control volume and source selection.
ANKits provides detailed build manuals designed to guide you through the assembly process. While it is a rewarding project, it requires basic soldering skills and an understanding of safety protocols when working with high-voltage tube electronics.
Yes, the design is highly modular and popular among enthusiasts for its upgrade potential. You can easily experiment with different brands of EL34 tubes or swap out capacitors to fine-tune the sound profile to your preference.
The amplifier achieves its quiet operation through a combination of a robust mains transformer, high-quality Mundorf capacitors, and a custom-designed PCB that optimizes trace lengths to minimize interference.
