LM-512CA Preamplifier

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
