Pioneer SX-828


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.

Awesome rvintage receiver ! IMHO, the best Pioneer of the 70’s range of all that I’ve owned. Had it totally recapped plus retransistorized key boards like the PS, Prot, Main Amps, EQ. Like brand new now good for another 40 years, lol. Unbelievable FM reception, too. Got it for a steal (many issues since completely resolved).

There’s a reason they’re hard too find. You’ll have a hard time prying mine out of the clutches of my cold, dead hands after my funeral, lol !

A very handsome and powerfull unit. Super build quality all round and am very proud of the one I own. Pity they dont make them anymore but to all vintage Hi Fi fans if you get one in good working condition snap it up.



re: SX-828

Two Issues :

1) FM works great though the FM board is the only board with all-original components. Should I replace the caps ? If yes, will it be necessary to re-calibrate the board afterwards ? Or with more in-spec uF value caps will the tuner board work even better ?

2) There’s no Tone Cancel Switch. I wonder, by putting the the Bass and Treble at the mid-point, would that qualify as a Tone-cancel or Tone-neutral sound ?

Thanks in advance

re: SX-828

I bought one of these back in the day and still own it...but time to let her go. She has not been used in 15 years but plugged her in the other night and she lit up just fine. I didn't have any speakers to connect to her so not sure if the sound is there or not but have to believe it is. The FM Antenna mount broke at the pivot ball but other than that it is in good condition....and it is for sale so if anyone is interested, message me. I am in Colorado.

re: SX-828

How much are you asking for the sx 828 receiver. I use to have one and want to go back to something that will last. I do not want any more digital units. Would it be possible for you to test it out with some kind of speakers to see if it has out put.

Thank you;

I just bought this beautiful receiver on craigslist for $100. I am a novice at this vintage equipment because in the early 70's I had the cheapest Panasonic equipment imaginable and in the 80's I had digital hk components and little knowledge. What I'd like to know is what are my parameters for buying speakers to match my receiver? Where can I find this info?


Just acquired an 828 myself. Sounded pretty rough when I picked it up but a quick cleaning and a bit of deoxit have it singing sweet. Running a pair of Polk Monitor 7's and they sound smooth. Having no trouble pushing the speakers. For a larger room than 12x15 the Monitor 10's would fit the bill. Each to his own taste but I'm enjoying the hell out of this set up!


This will allow me to view schematic details and keep my stereo for a very long time.
Much appreciated!

Thank you

Thanks for posting the SX-828 owner's manual. This is one of the few manuals I've lost for equipment that I own. I know the receiver inside and out, but it's still nice to have a copy of the manual on hand, if only for nostalgia's sake.


Thanks for the service manual along with the schematic of the SX-828 receiver. Having these valuable documents may help me diagnose a problem I've been having for a bunch of years. I had a couple of questions about the relay.
Thanks again.
