Pioneer SX-737

Pioneer SX-737


The Pioneer SX-737 was a mid to higher end stereo in their lineup of the SX-424, SX-535, SX-636, SX-737, SX-838 receivers. Produced in 1974 it churns out 35 watts per channel. Pioneer advertised it by saying: It has the power to do the job - not too much and not too little.  That about sums it up. It retailed for about $300.

The SX-737 really is a nice looking receiver. The blue dial light and meter are accented by red and green indicator lights. Add in the wood cabinet and brushed aluminum face plate and it exudes that vintage audio look.

It has the usual array of features one would expect in a mid range stereo. The FM front end is equipped with a frequency-linear 4-gang variable capacitor and dual-gate MOS FET. FM reception stability is enhanced by its multiplex demodulator with the Pioneer's PLL (Phase Lock Loop) circuit.

One interesting feature of the SX-737 that you don't see on many other receiver of the time is the Recording Selector option that allows the user to record an FM station while simultaneously listening to an LP, or vice versa. The build quality of the SX-737 was good but they are known for blowing output transistors occasionally. Over 40 years after it was introduced they usually need some of the electrolytic capacitors replaced in order to function as they should.

Pioneer receivers are always popular and the SX-737 is no exception. They sold quite a few of them so they aren't rare. But, the desirable mix of aesthetics and performance make it a good receiver for vintage audio enthusiasts. A really nice, serviced, fully functioning SX-737 will sell for about $250 to $300. But, an average good working unit can be had for $150 or so.

  1. I’d recommend this receiver to anyone whether newbie or collector. It’s got great sound, awesome phono stage and excellent build quality. It should be noted that the Pioneer x3x line also includes the SX-1010. I own both and while the 737 is NOT a 1010, I like to think the 737 as sort of a mini 1010 if that makes any sense.

  2. I bought my SX 737 while I was stationed in Germany 1975 at a electronics store in Frankfurt that only sold to American Military. I have used it every since everything about it is great. But after the years of use the left (channel) speakers fade in and out, I think it’s probably going to quit any time. Is it worth the money to fix it or should I replace it? What’s your thoughts?

  3. If you really like it then I would have it fixed. They’re worth about $250-$400 in nice working condition – more if a technician has gone through it and it’s mint. It’s possible it could be a simple fix. If you have someone nearby that can check it out and you don’t have to ship it anywhere then it would probably be cost effective to have someone go through it. While it’s on the bench you could have them go through the power supply and bias adjustment and other things to make it good as new. Definitely worth having someone at least look at it. HERE are recent sales on eBay. That’s my two cents anyway. 🙂

  4. Thanks for the info. I don’t know were you live, I live close to Reno, NV. Do you know of any trustworthy shops in the Reno/Sparks, NV. area that could look at my receiver?

    Thanks, Ed

  5. wow… i also live near Reno and was recently given a Pioneer 737. I hooked my dvd player through the aux inputs and hooked up some rather small/cheap Phillips speakers from the stereo that i had previously owned. It sounded great for a few days and then the sound began to cut in and out and the volume would drop. I assumed that i needed to get better speakers but now i think that the receiver is in need of service. I can’t imagine that it has been used much in the past few decades. It looks great and i want to use this as my home stereo but also do not want to spend a lot of money on something that i got for free…
