834mm Tube Stereo Phono Amplifier (Moving Magnet) — 20W per Channel

The 834mm tube phono amplifier employs a classic tube topology to deliver warm, full-bodied sound with fine musical detail—an excellent choice for audiophiles and hobbyists who value tube coloration. This single-board stereo amplifier is designed for Moving Magnet (MM) phonograph cartridges and produces 20W (per channel), making it suitable for a variety of home audio setups. Driving impedance options of 4Ω and 8Ω ensure broad speaker compatibility. Assembly is straightforward so even users without professional experience can complete it, and the board is engineered for easy maintenance and future upgrades — components can be swapped by the user as needed. High-quality capacitors and resistors are used on the amplifier board for stable signal transfer, while the tube-based design adds additional layering and enriches overall sound quality.
