FEATURES :
Feature:
These a pair of Power amplifier is a low internal resistance of the power transistor (845), it is Class A single-ended amplifier, the sound quality is good.
Power amplifier drive circuit as "SRPP" circuit, and for the dual parallel, wide frequency response, pushing strong.
Japan imported the audio output transformer using dedicated oriented silicon steel Z11 (0.35mm thick) and oxygen-free high strength enameled wire and special winding process multi-group production, so that the machine wide frequency response, to ensure that the machine high, medium and low frequency sounds good , transparent and powerful.
This machine adopts foreign name Factory sound dedicated enthusiast and non-polarized electrolytic (MKP) Need for high-quality imported French Suren gold blocking capacitors and manufacturing, the main audio channel dedicated to use imported from Japan (ALPS) volume motor potentiometer, with quiet background music, low noise, no sound pollution and durable.
High-voltage power supply for the automatic delay control, can effectively extend the tube life.
