Based on the Maranz SC7-S2 preamplifier circuit.
Power supply board: filtered by two 10000UF/35V NOVER capacitors, with sufficient energy. The voltage regulator composed of field-effect transistors K246 J103 and 2SD1415 has lower internal resistance, and the output filter uses gold ELNA capacitors, all for good sound quality
Amplification level: Use gold ELNA capacitors, CBB uses German MIMA capacitors.
Core amplification part: Use more than 30 pairs of A970 C2240.
