This was the small tube amplifier OEM by APPJ for Miniwatt & other brand and was exactly the same model as the highly acclaimed Miniwatt N3 amplifier, which was selling for US$378
Chassis was in sand-blasted aluminum, either in Silver or Black colour. High grade components found throughout the whole unit, including the Japan made output transformer, which was a main contribute to the sounding of this little machine. Ceramic tube sockets are used, just as those hi-end units.
This little machine was a single-ended tube amplifier using 12AX7 (ECC83) as driver tube, with EL84 (6BQ5) as the output tube, delivering a sweety 3.5 watts output per channel. Small power though, but driving ability would sure far beyond your expectations. You could also subsitute your own favourite NOS tube, like Mullard, Phillips, Telefunken etc to suit your preferences too.
Just remind you, don't let this tiny jewel size machine fools you. This was actually a very serious & addictive tube amp made for audiophile, not just only for bedroom and small living room indeed.
The unit comes with a universal transformer (100 to 250v). So it can be widely used in different countries without necessary to have any internal adjustment.
Safe Transportation: The unit was fully covered by foam, extra safe packing as seen from pics!
