This tiny unit, measuring 3.5 inches tall x 5.5 inches wide x 4 inches deep includes two 6H3-n vacuum tubes, and a solid-state amp offering 80 watts per channel. Included in the original box are:
The integrated amplifier with an output VU meter, a four-line-level input selector, a 1/8” stereo headphone jack, treble and bass controls, and a volume knob. On the back are four RCA input jacks, two five-way speaker terminals, a power switch, and an input jack for the 24VDC power supply. The power supply is included.
NOTE: This unit has no remote control and is therefore better used as a headphone amplifier or else a computer gaming amp. User manuals are available online.
