Product features:

●With four high quality nickel sheet/POE film alloy high quality wide rang EI as input and

output of audio signal input/output transformer coupling

●Using specially designed for the native EI type double power supply transformer

 (independent) around a track

●Use 6KZ8 as voltage amplifier output stage in 6922 as drive pipe, the RCA 22DE4 as

high voltage rectifier rectifier bravery

●Left and right channels completely independent design, and strive to two channel tone

●At the cost of using Multicap audio capacitor, the IRC resistance, axial capacitor, philips

BC panasonic relay, gold-plated CMC electric woodwind, high-quality RCA terminal,

balance the socket

●Function of infrared remote control can make audio input selection, volume and mute

remote control operation

●Successfully to the intuitive having a unique style into the volume dial design like that

design idea of the atmosphere

●Boot mute delay function (about 30 seconds)

●Selects the Japan ALPS high-grade motor potentiometer

●Convenient installation drawing plug-in valve cap
