SMSL T2 - 2X6J9 Hi-Fi Vacuum Tube Headphone Amplifier Find it on Amazon: http://amzn.to/2AD7mla Coupon Code: KSI8S2PC (20%off) Details: Low Ground Noise: There’s no buzzing or ringing when you use our amp! We feature a high-grade microprocessor that controls the relay while its being switched on and off, achieving a low-ground noise power circuit. Sophisticated Design: Our amp is constructed from top of the line, scratch resistant CNC aluminum.(Warm tip:When you use this product for a long time,please do not touch it by your bare hand,it may very hot,but please don't worry this is a normal phenomenon.) High Drive Current: Our specially designed power output boasts a larger than average drive current. Semi-Set Tube Design: As a safety measure, the high temperature portion of the tube is strategically placed inside of the amp and out of reach. Small Compact Size & 2 X 6J9 J-Grade Tubes: The dimensions of our amp are 2.9inX3.5inX1.02in, and you can replace the stock tubes with E180F, 6ж9П, EF861, and 6688 tubes if you wish to be able to cue music. Our T2 amp utilizes two 6J9 J-grade tubes and two NJM5532D as core parts of the circuit. The 6J9 tubes amplify the voltage which increases the input signal. The current formed by NJM5532D (Made by JRC Japan Company) amplifies the electric circuit to drive the mini headphone amplifier. These two features provide an awesome combination of high quality sound and a very powerful drive current for an optimum listening experience! Our T2 amp adopts a Single Chip Microcomputer and Relay to control the muted sound when the device is OFF or first turned ON. It allows the device to warm up before transmitting sound, protecting the unit and your speakers and preventing that annoying “popping” sound that is heard with many other, less quality systems. Please Note: The blue LED lights will flash for about 35 seconds when the unit is first powered on. This indicates that the unit is warming up. The blue lights will be lit solid when the amplifier is ready to be used!
