I just picked this up to go with my TC-229SD cassette deck and I love it! You could buy these by the pound...Fudge this is heavy, must be more than advertised. Well it is what it is, personally I like having a lot of controls to adjust and this has about as many as you could ask for except maybe a midrange knob. The sound is the best I've heard out of my own equipment and it has retro appeal of course. I can summarize by saying it's a keeper!

The STR-6800SD was loaded with features that few (if any) other brands offered in its time or since. I just bought one of these heavy 160W monsters and am very impressed with it. It has a nice sound, with a hint of tube amp darkness to it, coupled with nice definition. It is rated at 80W per channel at .03% THD at normal listening levels or .15% at full tilt.

The test speakers were a pair of mid-80s Mission 737 Renaissance (21 tall bookshelf)-2 way, with a 1979 Technics SL-D2 direct drive turntable with upgraded RCA cables. The cables allow me to run a cheaper cartridges and still get great results. The cables make a huge difference in the sound quality of the table. I put on a pricier AT125LC Audio Technica cart considered a legendary vintage great for rock. Then the setup started knocking my socks off. Everything became more detailed and realistic. I then started finding its tone addictive.

When playing vinyl, it has an almost haunting tonal quality to it, especially when you play the blues or blues rock. Its sound is similar to my Sony STR-V5 or should I say the V5's tone is similar to the STR-6800SD? The STR-V5 came in the next generation. This one may have a better sound than the V5 or the 6800 may just be in better condition. Both are great receivers and you won't be unhappy with either one.

I am not tech savvy enough to explain all of its features, but it seems like every feature was done better than what the other brands were doing at the time or have since.

No simple on/off loudness switch for this unit! Instead you can boost tones in 3 different volume ranges!!! I don't know of another receiver that offers that.

It has 3 speaker inputs, not 2 like other receivers. You can only run 2 pairs of speakers at a time apparently according to the speaker selector switch.

It handles two turntables and the standard 2 tape decks.

The tuner is stand-alone first class and as good as it got in 1976. Dolby FM may be a thing of the past, but it has that techie mid-70s feature.

This receiver was made 1976-78. Apparently its MSRP retail was around $600. There was one model above this one-the STR-7800SD, which was apparently very, very scarce in the states. Sony did better with their receiver lines outside the U.S., especially in Canada and Europe.

The receiver's cabinet and faceplate styling was a little behind in some respects compared to the other more mainline stereo brands being sold in the U.S. It does look a lot like Sansui receivers made earlier in the 70s. However, the quality of the parts comprising its exterior and controls is as high as any other manufacturer and superior to most of them. The faceplate, graphics, knobs and controls are better than first class and as good as I have seen on 1970s receivers! Once you turn this receiver on, you aren't going to care what it looks like, because it is what is sounds like that is important in the end.

I haven't looked inside the cabinet yet, but have seen the inside of the next generation of Sony receivers of the V3, V4, V5. Based on those experiences, I expect to find nothing but the best design and parts for its time and a huge amp. (This weighs in the low 40lb. range) Sony didn't leave out 10 cent parts to pad the bottom line like many other brands did in that era. Sony may have cheapened its equipment after 1980, but in this period they were the cream of the crop. Most Americans just didn't know about Sonys in the 70s.

You can tell just by looking at the outside that this wasn't some cheap 1980s Scott receiver. You could put this up against a Marantz any day and all day long. It was cutting edge for the 1970s.

I just got this receiver today, so I haven't had much time to experience all it has to offer. Couple that with the fact I am not audiophile material and so I am not going to elaborate much on this fantastic unit's numerous features. Suffice it to say, I really like it!

My first impressions are that I made a great score on this unit at less than $150 with shipping!! It has all of its knobs, a beautiful faceplate, controls and nice vinyl veneer. I am going to have to replace its light bulbs, but other than that it seems to be pristine. It won't be leaving my receiver stable any time soon.

I would give it four thumbs up, if I had that many! This is one of the best receivers made in the 1970s.
