MUZISHARE X50 Amplificatore valvolare KT170 Amplificatore audio push-pull ad alta potenza 130 W*2

Specifications:
Machine Features:
1. Purely handmade, the entire machine is constructed using sheet welding;
2. 1. Two high-end, high-quality EI-type output transformers with a 280W Z11 iron core, featuring advanced special processes and a wide frequency response, effectively improve audio signal conversion efficiency and broaden frequency response.
3. A large-capacity 2KW toroidal iron core and special materials are used in the high-power power transformer.
4. The preamplifier uses two Russian 6SL7GT vacuum tubes for voltage amplification and two Russian 6SN7EH vacuum tubes for voltage driver, resulting in a full, rounded, and detailed sound.
5. The power amp uses four Russian TUNG-SOL KT170 beam quadrupole vacuum tubes in an AB1 push-pull configuration for power amplification, providing transistor and super-linear selection: transistor mode produces a soft, pure, and smooth sound, suitable for vocals and string music; super-linear mode produces an open, expansive, and powerful sound, suitable for large-scale, dynamic music.
6. Five signal inputs (BALANCE, CD, LINE1, PHONO, PRE) IN); The balanced input port of this unit uses a specially designed permalloy alloy balanced transformer;
7. It uses German Mcup audiophile-grade coupling capacitors and specially developed metal silver film polypropylene audio-specific coupling capacitors, NICHICON electrolytic capacitors, Teflon pure silver signal cables, high-specification pure copper gold-plated terminals and components;
8. External power tube current adjustment knob, current display, and dynamic output level UV meter;
9. Power-on high voltage delay and mute delay functions (approximately 30 seconds);
10. Uses high-end Japanese ALPS motor potentiometers;

Features MM phono stage function; Infrared remote control function; Easy-to-install pluggable vacuum tube protective cover; The sound is noble and gorgeous, with abundant dynamics and excellent control, suitable for enjoying various types of music;
