Yaqin MC-18S EL34 tube push-pull Amplifier HiFi tube Amplifier

Features:
1. The pre-amplifier utilizes three Soviet 6H1P tubes, ensuring signal purity and wide dynamics.
2. The power amplifier utilizes four EL34 tubes in a Class AB1 push-pull configuration, providing powerful power.
3. A superior ultra-linear push-pull amplifier circuit ensures strong low-frequency thrust, rich tones, and distinct layers.
4. The pre-amplifier utilizes a common cathode amplifier circuit and a "long-tail" inverter circuit, resulting in a wide frequency response and low distortion.
5. A precision PCB circuit structure utilizes hundreds of components in a standardized and rational layout, minimizing interference and ensuring greater consistency.
6. Tube amplifiers are characterized by high voltage and low current circuits, placing high demands on insulation. The PCB perfectly meets these requirements, ensuring safety, efficiency, low noise, and stable sound. 7. The transformer is manufactured using 0.35mm thick, audio-specific silicon steel sheets imported from Japan, high-strength oxygen-free copper enameled wire, and a unique multi-layered winding process. This results in a wide frequency response of 5Hz-60kHz, ensuring the MC-18S delivers warm, rich, transparent, and powerful high, mid, and low frequencies.
8. All products undergo a 48-hour continuous burn-in period, and the core components, the output transformer and power transformer, are warrantied for 10 years.
