Features:
Use imported HIFI capacitor filter capacitor (Netherlands's Philip, Japan's ELNA, Japan's Ruby, etc.).
Coupling capacitances adopt Netherlands, Philip HIFI-class audio-specific capacitors; sound transparent is elegant, passionate.
Corners aluminum column: high-grade aluminum CNC machining, diamond knife speed car system.
ALPS’s volume potentiometer, Philip’s audio capacitor for Coupling and Power filter, Panasonics audio capacitor for Cathode compensation, Taiwan’s Military-grade 5 ring resistanc
adopt Japanese SUN classic lines improvement, every channel uses 2pes three common cathode tube parallel amplification with high output voltage
Has characteristics of driving current, full sound fast, transparent treble and smooth
Adopt high-voltage full-wave rectifier tube up to 315V +315 V, import core power inductors, r-type power supply filtering, import Philip / ruby supply filtering
Pure hand-scaffolding with Star Architecture(BOYUU’s special architecture)
Power tranformer:
Use 0.35, 96-50 large power core manufacturing, design power of 200W to ensure adequate power and low temperature rise.
Use high-quality oxygen-free copper enameled wire enameled layered tightly wound, with extremely low no-load current characteristic, quiet operation, no vibration, no hum.
Output Transformers:
Use potting output transformer with 0.35 thick high-flux silicon steel to ensure stability and reliability, especially in damp places, have a more reliable
performanc
Output transformer, is high-purity copper wire enameled wire package, and layered segmented string and connection method, three clips two wound
Output transformer with high-grade stretch cover, surface temperature paint handling, and bright fringes processes.
