Stereo tested and in working condition. Large (huge!) format amp made in Japan, 70 watts/chn @ 6 or 8 ohms, A & B speakers, 4 analog inputs (including phono), Dual Voltage, Switchable graphic EQ loop, Built in switchable echo, Mixer side with controls for Mic/guitar/line inputs (requires custom Pioneer cabling not included) Rare vintage piece and quite unusual! NOTE: The soft select Tuner select button on the bottom half of the unit is troublesome to activate. it requires numerous pushes to get selected (it will eventually select as you can see in the picture), however the related hard select tuner button on the upper half works perfect and can be used to select that input instead/as well. Also the mic/line/guitar side has not been test due to lack of the Pioneer cabling, though have no reason to believe it doesn't work as intended. There is also some staining on the back corner. Sold as-is due to age.
