Circuit characteristics
Pre-"SRPP" circuit, wide frequency response, low output impedance.
After stage amplifier for the low internal resistance of the power transistor (845), and for the CPI (A) single-ended amplifier,good sound quality.
After class to promote the circuit as "SRPP" circuit, and parallel twin-tube, wide frequency response, push strong.
Output transformers are imported from Japan Audio oriented silicon steel Z11 (0.35mm thick) and oxygen-free copper high strength enameled wire and special winding process hierarchical grouping production, wide frequency response of the machine, to ensure that the machine is high, medium and low-frequency tone well, transparent and powerful.
The machine adopts the best capacitors and precision gold blocking manufacturing abroad for factory audio enthusiast electrolytic and nonpolar (MKP), the main channel audio dedicated Imported from Japan (ALPS) and the volume of motor potentiometer, with quietmusic as background, low noise , no coloration, and durability characteristics.
The high voltage power supply for the automatic delay power control can effectively extend the tube life, and with full functionremote control.
Large VU meter for the volume indicator can be professional, to accurately reflect the volume size.
Each channel using 20000μf two channel machine a total of 40000μf large pond capacitor for DC to consider wave circuit power supply to the filament, so that the machine with extremely low noise, better sound quality.
