Pioneer SX-1050

Pioneer SX-1050

Another of the silver faced Pioneer line the Pioneer SX-1050 was the little brother to the giant SX-1250 in 1976 and 1977. While it may not necessarily be considered a “Monster” receiver it is close. It weighs in at just over 50 pounds and has many of the features of the top of the line SX-1250.  It’s rated at 120 per channel into 8 ohms as compared to the SX-1250 which was rated at 165 watts per channel. There were some fairly significant differences between the lower end Sx-850, SX-950 and the SX-1050.  The SX-1050 incorporated a large toroidal transformer, a huge power supply with step-start circuit and two large capacitors, a step attenuator volume control, a shielded multi-gang tuning capacitor, and a well improved FM tuning section as well. So, the SX-1050 is really far more comparable to the SX-1250 then it is to the SX-850 and SX-950. It retailed at around $700.00.

The Pioneer SX-1050 was eventually replaced by the SX-1080 in 1978.  The SX-1050 can be had for fairly reasonable prices. While the SX-1250 and SX-1980 are icons of the collecting world and therefore command sometimes ridiculously high prices an average SX-1050 in good working condition can be had for $500-$600. A really nice one will bring over $1000. Not bad considering its build quality and performance.

  1. I still have my SX-1050 from 1976. I bought it at the military exchange in Mildenhall, England for $360.00 (No tax). It is still in use today.

    1. I did the same thing I too bought mine In milldenhall AFB aka moldy hole then I would head to norwich on weekends and bang those English girls harder than a loose screen door in a hurricane! Wonderful memories indeed!

  2. babyboomer. got my sx 1050 new in 1976.still blows up my 4 cerwin vega spks. kenwood equalizer 1978 tames them. great sound! gran kids ( teens) call it prehistoric but bring their cd”s over to jam !

  3. I realize this was written in 2011, however, in 2018/19 you’d be hard pressed to get a 1050for under a grand. I have one pushing original series I Bose 901s from 1968 with a Pioneer 707 RTR and a Technics Sl-10 turntable with original cartridge tetipped last year by Soundsmith. Increible sound all around.

    1. I would agree to some extent. For a really nice, serviced SX-1050 they are definitely over $1000.00. In the last couple months there have been sales of $1395, $1350 and $1180. All for really nice units. But, most of the sales were in the $700-$900 range with about 8 sales in the last couple months. Less than that and you’re looking at models with issues of some sort. A parts model sold for $400. The SX-1050 is a great receiver. Sounds like a nice setup you have. I like the 707 reel to reel. Have one myself.

  4. I love my Pioneer SX-1050!! Really need to find parts for it. Its the best damn stereo I ever had!!! I wouldn’t want any other stereo!!!😊😊😊

  5. I usually won’t settle for 2nd best but in the case of the pioneer SX-1050 vs SX-1250 which is streaming for $1200 to $2300 I found it easy enough to bow down to the 1050 and its 120 wpc and considering it has much of the same features as the 1250 I went all in and walked away with a SX1050 in excellent condition for a bid of $666. It’s in the year 2019 of November and I guess the SX-1250 will have to wait and see how captivating the 1050 becomes before we even start thinking about upgrading..

  6. Found a Pioneer sx-1050 in November 2019 at a local GW for $59. Nothing was wrong with it except low volume from one side of the unit and the lights were out. After a $250 service i was all in $309. i will never part with this unit it sounds amazing.

    1. I have a Sx 1050 I bought in 1979 it still works . I have had it serviced over the years but man I would have it no other way . Out of all the material things I have ever bought this is the best one . Enjoy your receiver man !!!!

  7. I had the 1050 through the 80`s. It was a monster, really large case. The receiver I guess needed some restoration since it always had at least some background noise.
    I don’t remember it feeling like 120 wpc. I just don’t remember really. I wish I remembered where I got it…and I don’t remember what I did with it, but I can say I discarded it because I didn’t feel it was that impressive and worth the sheer monstrosity of the thing. I won’t recommend it considering radio broadcast is not what it once was and the tuner was a big part of the unit’s value. If it hasn’t been refurbished and re-calibrated I would definately not recommend it.

  8. About six years ago, I found a mint SX-1050 at a garage sale in my neighborhood while I was out for a walk. The seller was asking $50, and must not have known what he had. To be honest, I didn’t know what I was buying at the time either. I offered $35, because that’s all I had on me. The seller obliged. I still regard this $35 receiver one of the best purchases I’ve ever made.

    1. …wow

      $35.00, out-the-door !

      About 8 or so years ago, (2012), I purchased 3, mint/near-mint SX 1050’s @ $1000.00 each *add $100.00 shipping*


      In every way !

  9. I have wanted one for awhile . I just refoamed all 18 drivers on a set of 901 series 3 speakers, the Bose EQ is being upgraded but my 60wpc Onkyo isnt strong enough. I am now bidding on a SX 1050 on ebay. Hope I win.

  10. Hace unos meses compre un pioneer sx 1050, despues de haber probado varios equipos con preamplificador y amplificador de potencia separables, noté su buena calidad de sonido con frecuencias bajas contundentes y su buena recepcion de fm. Creo que voy a tenerlo por un largo tiempo a esta maravilla vintage.

  11. I bought my SX 1050 new back in 76/77 time frame. I have not used it for years but I am now in the process of setting it up again to be able to play vinyl records through it. I have a Hitachi Stereo Cassette Tape Deck, D-900 and a ADC Sound Sharper Stereo Frequency Equalizer connected to it along with the Dual turntable. The speaker system is Bose 901’s (recently rebuilt). My question – does anyone have any idea on the proper setup of the connections to each device – and the SX-1080?

  12. Bought a mint sx-1050 from a Technician in Canada fully restored with upgraded blue filter caps for $1,650. Not for resale but for myself. My opinion it’s more affordable buying restored than buying and shipping out for restoration .. The sx-1050 with my 901s sound strong and have great stereo separation..
