MUZISHARE X20 Class A 300B 845 Tube Sinle-Ended Integrated Amplifier & Power AMP

Features:
Pure Handmade, the whole machine is scaffolded point to point hand welding.
Two EI single-ended output transformers with high quality special process and high quality wide frequency response made by Z11 core
Use a high-power power transformer with a Z11 core and special materials.
The front stage uses 6SL7 and 6WG7 with two empty tubes: the push part uses two 300B tubes and pushes the transformer to the rear stage, and the sound is full and round and dynamic.
The latter stage uses two 845 vacuum tubes for Class A single-ended power amplification.
Power on mute delay function (about 30 seconds).
Five groups of signal inputs (BLANCE, CD, Linel, Line2, PREIN): This unit has a special balance input function and pure post-level function.
Volume and mute function remote control.
Start high voltage delay and silent delay function (about 30 seconds).
High-end dual-pointer output current and level dual-use meter
Select Japanese ALPS motor potentiometer
Easy to install in the plug-in vacuum tube protection
Peripheral power tube bias current adjustment function.
