Bluetooth5.1 Version MT-35 MK3 HiFi Electronic Tube Power Amplifier 36W+36W 4xEL34 Vacuum Tube Amplifier with VU Meter

Bluetooth5.1 Version MT-35 MK3 HiFi Electronic Tube Power Amplifier 36W+36W 4xEL34 Vacuum Tube Amplifier with VU Meter

Configuration:
- Voltage amplification: 1 x 12AX7/ECC83 to ensure pure signal and wide dynamic range.
- Driving: 2pcs 12AU7/ECC82, enhancing signal driving power while preserving detail levels.
- Power amplification: 4pcs EL34s are used for class AB1 push-pull, providing high power and warm and full tone.

Features:
- The power amplifier circuit has undergone a comprehensive new upgrade, with the use of superior components, achieving a significant increase in output power and taking an important step in adaptability, which can be compatible with and drive more types of speakers. At the same time, the main performance indicators of the whole machine have also been greatly improved, and every detail of the music can be truly displayed. Frequency response: 8Hz~60kHz (-3dB); Total harmonic distortion: 0.25% (1kHz); Signal to noise ratio: 93dB

- Providing transistor and super-linear selection functions, which can be switched with one click on the top panel.
  Transistor working mode: the sound is soft, pure, and smooth, suitable for appreciating types of music such as vocals and strings.
  Super-linear working mode: the sound is loud and unrestrained, with a good momentum, suitable for appreciating music of large scenes, dynamics, and other types.

- Upgraded aesthetics, the aviation aluminum alloy panel is matched with the gray sandblasted plastic process on the fuselage, which has good wear resistance, corrosion resistance, and weather resistance. The panel and tube cover design have been refreshed, with sturdy and smooth lines flowing between them, adding a touch of high-end texture to the home space and showcasing extraordinary style.

- Multifunctional VU meter design: dynamic power meter + BIAS meter, dynamic power meter compatible with BIAS monitoring function. When used as a power meter, it can display the output level value of the power amplifier; When using a BIAS meter, display and adjust the bias state of the corresponding power amplifier tube. At the same time, the external EL34 vacuum tube current adjustment (BIAS ADJ.) adjusts the bias voltage of the corresponding vacuum tube. Humanized design keeps the power vacuum tube in good condition at all times.

- Using for ALPS imported potentiometers to ensure smooth and accurate volume adjustment, maintaining signal purity and reducing distortion and noise during the volume adjustment process. When adjusting, you can feel the smooth and unobstructed rotation feel, as well as the delicate transition of volume changes.

- Self-developed high-quality ring transformer: adopting a high-purity copper enameled wire winding design, which produces lower magnetic noise compared to standard transformers. Combined with specialized research on shielding packaging technology and circuit protection measures, further protect the amplifier circuit from noise interference and effectively improve the product's service life.

- The interior of the product is made using manual scaffolding and point-to-point wiring. Each MT-35 MK3 machine's internal circuit is carefully hand wired by experienced technicians using high specification wires and components. Ensure that the circuit has a higher channel rate, resulting in better sound transparency and delicacy.

- 3 sets of input terminals for the circuit; Supports 4Ω and 8Ω impedance output selection, compatible with multiple types of speakers; Supports 6.35mm headphone output, allowing one person to listen to music quietly.

- Standard vacuum tube protective cover, easy to plug and unplug, not only protects the vacuum tube, but also avoids accidental contact with the heating vacuum tube during operation.

- Anti-vibration and anti-interference, aviation aluminum alloy panel, high-strength metal shell, base reinforcement design, effectively reducing the impact of external environment on sound.
