Yaqin Yaqin MS-845 Preamplifier and Mono Blocks Combo,Output Power 25w,Tubes 12AX7/12AU7/845, with Remote Control, AC115 or AC230 Switchable 2025 - silver

--  A High-End Preamplifier and Mono Blocks Set: one preamplifier and two mono blocks

 -- The pre-amplifier drive circuit is devised as an "SRPP" circuit. It is characterized by a dual parallel configuration, a wide frequency response, and a strong driving capacity.

-- High-Quality Construction: The output power transformer is crafted from imported dedicated Z11 silicon steel and oxygen-free high-strength enameled wire, featuring a special winding technique. This results in a wide frequency response, ensuring that high, medium, and low-frequency sounds are soft, transparent, and powerful.

-- This set of tube amplifier combo utilizes audio-specific hifi-grade non-polar electrolytic  capacitors with renown brand and  high-quality imported gold-edged capacitors, the main audio channel utilizes  imported Japanese potentiometer to ensure a quiet background  with low noise, no sound pollution and high durability.

 --A high-voltage power supply furnished with automatic delay control can effectively safeguard the valves and extend the service life of the tubes.
