Bought mine new in 1980 (or maybe early '81) from the venerable Wisconsin Discount Stereo (they were big advertisers in the old Stereo Review magazine). In my opinion, this series of receivers (and this entire series of components) was Pioneer at its pinnacle. The styling and the feel was just as important as the sound quality, but never more important. Hell, even the Pioneer logo was better back then! The 45 watts per channel rating always seemed conservative to me, because this thing could play loud and clean all day long. Great tuner section too...love the combination analog/digital display. Funny to think that I could sell this today for more than I originally paid for it...but that'll never happen. This is a great receiver. If you want a good foundation for a mid-priced vintage audio system, you won't go wrong with a 3700.

I absolutely love this receiver, it is very beautiful, I bought mine from vintage audio dealer a little outside my city, I had my mine set on something else, but when he recommended this receiver and played it for me, I fell in love and my mind was made up, the owner of the store is an Pioneer head, he has all kinds of Pioneer equipment, my receiver looks brand stinking new and fully serviced

I scored this beauty at Goodwill for $10 and change. It is in perfect working order, except that one push button light is burned out. I have cleaned it and used Deoxit D5 on the pots and switches. I love this thing. Powerful, clear, present sound.

I purchased a 3700 used from Ebay. Normally I just don't like to purchase anything used, but my old Fisher 514 was wore out it just wasn't worth fixing, and I just didn't like the black faced plastic that they have been selling since the early 80's. Now the SX 3700 is one of the nicest stereo receivers that I have ever listen too. It has two tape inputs, one aux, and a phono input. It also has a digital readout on the tuner, as was as an analog dial. This is the machine that started the transition from real stereo receivers to the plastic junk sold today. This machine also has A&B speaker connections, so that you could connect up to 4 speakers. I only spent $118.00 including shopping, back in the day ( 1980-1982) these sold for about $375 . It delivers 45 watts per channel. This was the first of the upper tier receivers in the flouroscan product line. Both the power meter and the FM meter are blue fluorescent displays. This is also the first receiver in this line to have a 2nd row of buttons, and it was the first receiver to use the famous lever switches , although it still used a rotary switch for the on-off. The biggest downfall to these receivers is that when the push button lights go out, or when the rotary switches need cleaning, you must remove the entire front interior and exterior face plate. This machine is so nice cosmetically that you will just love the look, with its nice shinny aluminum surfaces. I would recommend a dust cloth be place over the top when not in use because the vent on this receiver goes across the entire top center of the machine... and as we all know dust is the worst enemy of electronics... so keep it clean and it will last you for years....

Just bought my beauty off of eBay for two hundred dollars in near mint condition. I love this beautiful component and it performs flawlessly

re: SX-3700

Just got one for 100bucks, in beautiful condition, it has a better sound that my Harman Kardon new 7.1 receiver. These are really Hifi systems for any music lover.
