SMSL T2 Vacuum Tube Headphone Amplifier, Mini Audio HiFi Stereo Integrated Amp

FEATURES:
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, fewer 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!
