Pioneer SX-650


Pioneer SX-650


One of the classic mid-range receivers offered by Pioneer in the mid 70's was this Pioneer SX-650. As you can see it has the classic silver face styling of Pioneer's 50 series which, when coupled with the wood case, makes for an exceptionally clean and stylish looking receiver.  The SX-650 was produced from 1976-1977 and sold for around $300.00.  The SX-650 puts out 35 watts per channel in to 8 ohms and was designed and marketed for those with an average sized listening room and who wanted good value for their money. The 650 didn't have to many frills but what it did it did well.


Pioneer SX-650 User Manual


The Pioneer SX-650 weighed in at around 29 pounds and its dimensions are: 19 x 6 x 14.5 inches.  For those with dial lighting issues the standard bulb in the SX-650 was an 8V 300mA globe bulb. Those are a little difficult to find these day so a good substitute is a 10mm  8V  .250A wedge bulb. They can still be fairly easily found and are not too expensive.

  1. Bought mine in 1977. I have it in my man cave & it stills kick butt. I plug in my phone & play pandora all the time.

  2. did it blow up or did it blow the fuse?
    I bought mine in 1976 and it is still going strong. Sometimes the contacts get dirty after 39 years and you have to flip the tape switches to get it to make good contact or you can lose 1 or 2 speakers.

  3. I had my SX 650 for 42 years, it finally went to the sound machine in the sky. One of the greatest investment in my teen years. It was like losing an old friend, last Friday garbage day. Some must be looking out for me. Because my eldest Son had a SX 750 in his garage he did want, and didn’t know where it came from. I’m a young 62 year old, and today I feel like a teenager all over again. LET THERE BE ROCK !!!

  4. I just cleaned up my father-in-law’s old SX-650 and pressed it into service powering the monitors in my mini home recording studio. I had to DIY some LED replacements for the dial lights, but beside that, a few spritzes of Deoxit in all the pots and switches got it back going strong. ’70s analog iron for a 21st-century laptop DAW. Yeah!

  5. DOH! If you’re using the aux inputs for an MP3 player or audio interface, DON’T FORGET TO CLEAN THE MICROPHONE JACK. If the switch contacts on the jack are dirty, it messes up the AUX signal. The Tape inputs are not effected by the MIC jack.

    Lesson learned.

  6. mine doesn’t have any sound except for some cracking noise,which seems to be coming from the left side of the receiver itself also the 3 lights are flickering.and the power switch knob wiggles somewhat. any suggestions?

  7. Deoxit that can be found at Radio Shack works very well for cleaning audio/volume control contacts. Worked like a champ on my SX 650.

  8. I have an SX 650 that has rust on the back extended part around the speaker connection area. Can anyone give me an idea how to restore that area?

  9. Get hold of sounds classic in Rockford il. All they do is refurbish classic audio. I’ve had them completely restore 4 reciever 2 pioneer, 1 marantz, and my monster Rotel. They do first class work at a reasonable price. They supplied all of the audio equipment for the HBO series vinyl. These guys are awesome I had a pioneer sx650 and xs780 refurbished as well as a Rotel 1203 and they all are awesome just like brand new. My marantz 2250 is there right now.

  10. Hey Darrell,
    For a point of reference, how much did it cost to refurbish the SX-650 and what, exactly, did they do? What parts were replaced etc. and how many hours of labor did they claim? This would be good info for everyone. Thanks

  11. Hi, I have one SX-650 that it´s making great noise..what do you think about?..I should give it to someone?
