The SX-828 is a big power AM/FM stereo receiver with advanced circuit design, outstanding FM selectivity and sensitivity, and linear scale tuning dial.
Here, in one of Pioneer's most prized packages, is a wealth of outstanding performance in an AM/FM solid state stereo receiver.
The SX-828 is another in the long, proud line of advanced stereo components from Pioneer - and certainly one of the best.
For music power that will fill any-sized room with clear, rich sound, the SX-828 features up to 270 watts (at 4 ohms).
For FM selectivity and sensitivity that has no peer in a unit of this size, the unit features a large linear scale tuning dial, the latest solid state circuitry, and a pair of FM tuning meters.
And, finally, for the supreme versatility that is so necessary to quality hi-fi today, it provides two tape monitor circuits for tape-to-tape duplication, and lets you use up to two turntables, three sets of speaker systems, two microphones and even too sets of headphones.
All in one handsomely-designed, ruggedly built unit from the quality stereo people at Pioneer.

The Unit is in good condition showing some age wear and sounds fine.
There is some minor noise on some of the pots when you move a switch or turn a  knob.
Nothing major in my opinion.
The receiver could use an inside cleaning of the pots and knobs.
Certainly wouldn't hurt.Get rid of any 40 year old dust, etc.
It is a piece of vintage electronics after all!
There is a small wood chipping area on the left side of the front wood panel (see photo).
I misplaced the original speaker jacks years ago. You can buy replacement ones on Ebay for around -29.
I checked the sound for this sale by inserting paper clips into the positive and negative part of the jacks and then wrapped speaker wire tightly around the paper clips allowing the speakers to be heard.
It's a Jury rig hook up, but it worked well
