About the TU-8600R/TU-8600S
The Elekit TU-8600 series, including the TU-8600R and TU-8600S models, is a single-ended tube amplifier kit that utilizes 300B tubes for exceptional audio quality. It is designed to provide a stable Negative Feedback (NFB) circuit, which enhances audio performance. The amplifier features a high-efficiency R-core transformer with individual windings for filament heater, high voltage, and bias stabilization, reducing residual noise significantly compared to its predecessor, the TU-8300R. The kit includes high-quality capacitors but also allows for upgrading with larger coupling capacitors. Key specifications include a power output of 9.2W per channel at 10% THD, a frequency response of 7Hz to 40kHz (-3dB), and an input impedance of 50kΩ. The output impedance is selectable between 4-6.3Ω and 8-16Ω. The amplifier supports both 110-120V and 230V AC power supplies, making it versatile for different regions.
