It is a Stereo receiver.

* One is on E-bay right now for $18.
Thanks for the link, Bob.
That was a low end unit for Technics.
If it still sounds clean and can get it for nothing or close, it may be worth it just to put sound in a room for cheap, but don't confuse it with high quality vintage electronics. Frankly, with the sliders I'd bet the controls are very noisy!
If you check this link, it was the least expensive unit in the list!

Technics did make some decent stuff. I have an integrated amp I bought in 1982 that is still working fine in my garage system. I think the fact that it still works like new after 27 years (I cleaned the pots once) says something for the build quality. However, it was never my "favored" amp.
I suspect Bob may be right that Technics may have fallen to Fisher-Price later-on, but they were competitive with their high end in the late 70's and early 80's.
My amp was mid-level and rated at 60W RMS X 2 from 20Hz to 20kHz at .005% distortion. I don't know if it still does that, but it will still crank without any sign of distress.
Even the cheesy FL power meters still work like new!
