Mr. Mon Tokyo SOUND ValveX-SE Vacuum Tube Headphone Amplifier

This is a Tokyo Sound Valve X SE vacuum tube headphone amplifier.

I received it from an acquaintance who had been carefully storing it for some time, so I don't know the details.

I have only confirmed that it powers on; I have not been able to test its audio output or other functions. Therefore, it is being sold as-is, as junk, with no returns or complaints accepted (NCNR).
