MUZISHARE X9 300B Ламповый несимметричный усилитель класса А Balance & Pure Integrated Amplifier

Features of this machine:

1: Purely handmade, the whole machine adopts standard welding
2: Use two high-quality, wide-frequency response and high-sound quality Japanese E-type transformers
3: Use high-power Z11 iron ring power transformer specially designed for this machine
4: The high-voltage part adopts 2 according to the light 274B for full rectification
5: The first stage uses two Czech 6SL7 and 6SN7EH vacuum tubes, and the latter stage uses two 300B vacuum tubes for class A single-ended power amplification
6: Peripheral power tube current adjustment button and current display and dynamic level UV meter
7: Choose Japanese ALPS motor potentiometer, use German Mondolfo M-CAP HIFI capacitor
8: Turn on sound function (about 30 seconds)
9: Infrared remote control
10: Easy-to-install pluggable vacuum tube protective cover.
