Triode amplifier mode, the sound is soft and smooth, suitable for enjoying vocals and strings. Super linear power amplifier mode, the sound is open and the sound field is wider, suitable for enjoying large-scale and dynamic types of music. Amplifier, two tones. The shell of the MT-45MK3 is carefully crafted with 14 spray paint and polishing processes. The front uses an aviation aluminum alloy panel and is equipped with a double-head design, which is both beautiful and practical. Double meter design, retro and eye-catching, a professional power meter that rhythms with the power, the speed is strong and weak, and you can feel the beauty of the music rhythm. Fully self-developed high-quality toroidal transformer It is designed with high-purity copper enameled wire winding, which produces lower magnetic noise than standard transformers. Coupled with the special research on shielding packaging technology and circuit protection measures, the power amplifier circuit is further protected from noise interference, and the service life of the product is effectively improved. It is made by hand-built point-to-point wiring. The internal circuits of each MT45MK3 are carefully hand-wired by experienced technicians using high-standard wires and components. BT 5.0 You can push music to MT-45MK3 for playback through your mobile phone or any music device that supports BT. MT45MK3 supports a variety of wireless high-definition music protocols including LDAC (LDAC supports up to 990kbps 32Bit/96kHz sampling rate high-resolution audio) Standard vacuum tube protective cover Anti-vibration and anti-interference Aviation aluminum panel, high-strength metal shell, base reinforcement design, effectively reduce the impact of the external environment on the sound. Power-on mute 60 seconds delay Protect the life of the machine, while ensuring that the preheating is sufficient to make a good sound. 1: Power switch (POWER) 2: Volume control knob (VOLUME) 3: Power level meter (left meter and BIAS bias meter) 4: 6.35mm headphone jack (PHONES) 5: Input selection knob ( SELECTOR ) 6:BT indicator 7: Meter mode selection power mode/bias mode (METER-POW/BIAS)* 8: Power amplifier mode selection transistor/super linear (TR/UL) 9: Vacuum tube bias adjustment (BIAS SEL/ADJ) (only used when replacing or debugging) *When it is necessary to replace and debug the vacuum tube, switch the METER switch on the upper panel to BIAS, that is, switch the left meter to BIAS bias meter mode. The state of the four power tubes can be tested by this bias meter. In normal use, keep the METER switch pointing to POW. On Oct 16, 2022 at 19:38:12 PDT, seller added the following information:
