Product technology:
Handmade scaffolding welding, there is concise and easy process, traces short, simple upgrade change material.
Imports of stainless steel chassis. There look gorgeous, durable, can not afford not peeling paint and so on.
Three tubes with ultra-linear transfer function, the perfect balance of push-pull machine play of strength and beauty.
Achieve internationally accepted proof output transformer potting processing, you can not damp decade, high stability and durability.
Unique aluminum pillars corners resonant structure principle, with the traditional bottom machine foot structure will have excellent stability and reliability.
Product design:
Voltage amplification 12AT7, 12AU7 current drive, KT88 push-pull power output.
500W power supply transformer adequate supply to meet large dynamic energy output, 114-80 import core transformer.
80W output transformer design, fine tightly around 5 clip 3, hierarchical segmentation, primary, secondary series parallel wiring, hiding foot high output transformer inductance and low leakage inductance characteristics, core import 0.35 for high silicon, stacked thick 96-50 core manufacturing.
Volume potentiometer, we made direct use of pure Japanese ALPS graphite film series, with left and right balance of high, warm sound, good dynamic characteristics.
it is Self-bias.
