Power Transformer: With 96-60 large iron core, 200W rated power and 0.35mm high magnetic flux silicon steel sheets, multiple composite vacuum impregnation technology. High-quality oxygen-free enameled wires with multiple-laying and intensive-wiring technique ensures its very low no-load current characteristics and no vibration noise.

Output Transformer: using high-quality plate and stretched transformer cover and JAPAN ultra-thin pure wood insulating paper. Classic input in series and output in parallel design adds high-inductance and low-leakage characteristics.

Power Circuit: using double high-voltage full-wave rectifier vacuum tubes 315V+315V, π type power filtering capacitances and imported Philips / Japan RUBY power filtering capacitances to filter the signal. Dutch Philips Premium audio capacitances as coupling capacitances ensures its clear and emotional sound output.

Amplifying Circuit: improving based on classic JAPAN SUN circuit design. Each channel adopts two parallel common-cathode triodes, which ensures its high output vlotage and large driving current.
