    😮 Quel souvenir ! J'avais pris le virus de la Hi-Fi grâce à mon père. Ce modèle fût mon 1er ampli acheté après avoir cherché dans tout Paris le meilleur prix et meilleur compromis pour le budget que je m'étais fixé.
    J'y avait associé une platine Akaï (ref ? avec cellule Ortofon elliptique), de bonnes enceintes B&W (ref ? taille moyenne) + tuner et magnétophone Akaï 4000 DB (Dolby).
    Je me souviens qu'on m'enviait le bon son que j'avais ! J'y écoutais toutes sortes de musiques, depuis du disco jusqu'à la musique classique en passant par du jazz. Que ce soit pour la Hi-Fi ou le reste tout était sympa et plus facile en cette epoque bénie !
    22 ans, retour du service militaire, 1er studio, 1er emploi, puis en 79 1ere voiture et vacances avec ma petite amie de l'epoque. L'insouciance, les espoirs et les rêves de ma jeunesse... La liberté, les sorties, les dicothèques, les bons amis et les jolies filles. Pas très riches mais la vie était belle et tous les espoirs permis. Aujourd'hui j'en ai bientôt 68 et combien je suis nostalgique 😢 de ce temps là...
    Bon son à vous tous les anciens comme moi ou les + jeunes ! 😊

    Looking at the schematics for this amp its a stunningly sophisticated design for a integrated in this price range
    with all the proper compensation and stabilisation parts in place that normaly got sacrificed for better profit.
    A pretty outstanding feature here is that the inputstages of the poweramps got separatly fed and can be precisely
    adjusted via a doubleset of trimpots (DC adjustment) per channel. The four blue lytics are additional filtercaps in
    the powerlines for the driver and outputstages of the poweramps to further lower ripple effects on the feeding
    power lines.

    My father has bought that before I was even born. I grew up spending hours in front of it listening to music either from an AKAI cassete player or a Sansui Tuner. It has been years since it has been used. I am now thinking of taking it to my house and giving it some maintenance (if needed). I hope it is still alive. Thank you for this video. It really brought back memories.

    Thx for this lovely and passionate review. I own this amp since I was 18 y old and recently did a full restauration because I wanted to last another 40 years :-)! I did afull recap,resistors exapt the transistors because they still measured good and quality is even nowadays exeptional. The blue capacitors are Nichicon, Sansui used for this amp mainly Elna and Nichicon capacitors. These blue ones are DC decoupling capacitors and can certainly have an effect on sound, especially dynamics and tight bass sound. I replaced them with 1.3x higher value Panasonic caps. Everething else as standard values as original. To me this amp sounds as good as any todays amp in the 1000 to 1500 euro range. Sound is not always about lowest distortion but feeling dynamics and emotion! Keep going,

    For any one interested in the au-117/217/317 range.
    I have a 117 mk1 and a 317mk1(both high-end re-capped) and am very familiar with the 217mk1 (my parents had this when I grew up).
    Power amp wise I was not getting the vibe from the 117mk1 that I was looking for (I was expecting like a 217), so I went for a 317mk1, and that did deliver (and then some). I would say sound wise the 117mk1 is 50% of the 317mk1 and the 217mk1 is 80% of the 317mk1.
    So if you have trouble finding a 317mk1(and you don't use the phono stage) , the 217mk1 is a pretty good alternative.
    The bigger difference is in the phono stage. Both 117 and the 217 share the same simple phono stage, (two transistors, electrolytic input coupling). The 317 however has allot more elaborate stage with 6 transistors and allot of nice polystyrene capacitors and a separate shield. Although I did not use my 117mk1 for record playback ( i do know the sound of the 217) , I was surprised at how good the phono stage quality of the 317 is.
    So if you plan to play records go for the 317. It might not compare to separate high end phono stages, but it is an integrated amp after all.
    The difference between the mk1 and mk2 versions is this:
    1: cheaper construction (no inlayed logo, thinner front plate(from what I can tell).
    2: no pre- amp out, power amp in on the 317.
    2: bump up in output power, and different transistors(at least in the output stage).
    They bumped up the transformer voltage and power supply capacitor section and changed some resistor values in the output stage to get these higher output values for the mk2 versions.
    MK1 output power:
    117 = 15wpc @8ohm
    217 = 30wpc @8ohm
    317 = 50wpc @8ohm
    mk2 output power:
    117 = 25wpc @8ohm
    217 = 40wpc @8ohm
    317 = 60wpc @8ohm
    I don't know if running the output section a little hotter like that(mk2) makes it a better amplifier (well, at least commercially it would).
    Edit: For the 317mk2 they actually lowered(!) the value of some of the decoupling capacitors in the output section! (the ones you were pointing at).

    I stumbled by change upon this review and it is as if you were describing my Sansui AU117, which I bought in 1978 and still use at my desk in my home office for playing music. I also still own the second amplifier I bought in 1987, a Denon, which was beefier in the Watts department and had a better performance on paper with regard to total harmonic distortion and such, but the sound was never so appealing , embracing and warm to me as my old Sansui AU117. After a few years of less satisfied listening experiences I swapped them around and kept the Sansui ever after as my preferred amplifier and the Denon in its box as a back up, and after so many years my AU117 is still going strong.

      @@stereoreviewx Certainly Yes. Better is to match with nice tube preamplifier, especially with 6922 tube. I got my system this way, and with higher gain of the preamplifier, much better in clearance in tonal definition and much wider in sound staging. This is amazing amplifier when married to Siemens E188CC/7308, the top definition mid and high, balanced, and clear back staging especially. Another way to uptrade sound is to use higher gain source with lower distortion. Preamplifer is both good with Aux in, or Pre in. To me, Aux was better. Not need to say that the sounds still staying within beautiful pretty Sansui. Just kinda add-up to Sansui thing. Try it.

    The 2 big black capacitors are filter (smoothing) caps for the power amp and the 4 blue caps do the same for the lower voltage pre-amp power supply. When AC (mains supply) is converted to DC (all amps work with DC current) there is still ripple (the positive 50Hz component of AC), thus it needs to be shunted to ground via capacitors (which only pass through AC current and block DC current).
    The filter caps basically remove unwanted noise (AC ripple) from the DC power supply.
    The secondary function of having big filter caps is to keep the DC voltage rails consistent when dynamic spikes suck the supply voltage down. They act like very low resistance batteries that can instantly top up the supply voltage the moment it starts to decline. Voltage always want to flow from the highest potential to the lowest. These types of caps must have a very low resistance so these can deliver the current essentially instantly. When caps get old they tend to dry up (electrolytic fluid inside) and the resistance goes up.
    If you see a cap that is bulged on the top (you can feel a small budge better than see it) then it is definitely gone bad. Capacitors can still go bad and look fine, so only an ESR meter can measure the internal resistance (without removing the caps) and determine if the caps need replacing.
    Kelvin, you are a smart guy, so I am sure you could easily learn the basics to safely check the caps (and replace them) in your plethora of gear. I have learned the basics of electronics, because it's too expensive to pay someone to do it for all the gear I have. A soldering iron and ESR meter is about $100. Most caps will be in spec, but power supply caps are experience the most stress. Most other components either work right or totally fail. Caps can degrade slowly and mess up the sound without failing completely.
    Also, you can replace the caps with better than original, because electronic component are much better today. Even on more modern electronics repairs I will buy high quality caps ($2 instead of 10 cents) for longevity and audio quality in audio gear.

    As having read from other posts the Black Caps are for the power supply and if it were me I would change them perhaps go 5 volts up and as much capacitance as you can fit in under the hood, in fact change all the caps for the cost of it. The resisters should be fine but none the less measure them all and consider replacement that will really open up the sound for you...if you live in Yorkshire drop it off if you want a hand.

Deep, rich tones, lifelike voices and tight, powerful bass, accurate 3D sound staging. It has it all! I then got hold of the more powerful AU-3900 and was disappointed by the comparatively flat soundstage and harsh brightness. I think the AU-X900 range is the one to avoid! And if I haven't emphasized it enough, do yourself a favor and get an AU-2200!

I'd been thinking the same thing about the STK modules and have been trying to get hold of a comparable amp that uses them. The Rotel RA-300 is a good contender, waiting for one at the right price. Otherwise if I can get hold of a 4400 and a 441, I should be able to know once and for all whether it's the chip or the rest of the amp that imparts the excellent sound (The 4400 being the closest to the 2200 without the chips). It's pretty strange, since most people seem to spurn STKs as being a crappy cost cutting measure. And in all fairness that's what they were, they've just accidently ended up making some excellent amps!

The main reason they were made I think was to save companies designing there own amp and size as they do not take up to much room and mounted upright. Sanyo seemed to be the main supplier, the ones used on these amps/receivers are the low numbers 14,15,16 etc, Goes in to the 4000's these days.
      Though I think Sanyo stopped making them about 20 years ago. Though plenty of rubbish Chinese clones about. I will be looking out for any amp/receiver from the 70's in the 10 to 20 watt range that may have one of these in as a comparison and report any findings on my channel. I also would have thought that the pre-amp/ tone circuit would play a big part on how these sounded. But as you say a lot of people seem to dismiss these amp on a chip STK's so making picking up a good cheap amp a little easier.

The speakers were a bust on my receiver but with this amp they were booming! I could only turn the volume up 2 clicks at night. Not sure why the speakers were night and day with the amp.

    Hi Kelvin, you asked about the capacitors in AU-317...the two black ones is 10.000uF/50V used for the main supply which is +-42VDC. The blue ones is 470uF used for the regulated supply of +-28VDC for preamp, phonopart a.o. parts....This is standard for a "complementary" amplifier with plus and minus transistors PNP and NPN in the output.....in your videos you like the type of amplifiers from 1969 to about 1975 where the topology mostly were "quasi" designed amps... which means, you have only one plus rail of lets say +60VDC and a pair of NPN output transistors that shares the voltage. Then one half of the supply of +30V is used by the upper NPN and the other NPN uses the other half of the supply..... (just short) in the middle you take the speaker signal out through a capacitor of approx 2.200-3.900uF that saves the speaker not to have the DC voltage across the voicecoil.....this is the basic of a "quasi" amplifier. The AU-317 is not a "quasi" amp but a complementary design..... the "quasi" designed amps used a pair of NPN's as output transistors because it was difficult to make PNP transistors with the same specifications back in 1969.... I have never heard the AU-317 but the schematic looks fine. Best rgds Kim DK

    I have this amp along with the sansui sr-636 turntable. I was wondering your thoughts on the turntable. Its my dad's and he bought it in japan when in the navy in the 70s. I use it regularly and love it but know little about the hobby. Great video and look forward to learning more about the hobby.

    The black capacitors are the power supply capacitors, the blue ones could be the output capacitors. Or they could be the power supply capacitors for the pre-amp (or even driver stage). In the latter case it would explain the quality of sound because it means that the pre amp stage and possibly the driver stage has a more or less independent power supply from the final stage. If they would be the output capacitors, it would mean that this design needs them and that is not as good as having a symmetrical power supply and a DC coupled output stage. The fact that they come in pairs is good news because it an indicator that this amp has a symmetrical power supply. BTW with that I mean that the ground level is in the middle between the positive and negative power supply voltage and not just ground at zero and one positive voltage.
    I would love to get a good Sansui amp, so thanks for mentioning this one. But I went on eBay and you can not find them for under 200 Euros (180 Pounds, so they are a bit more expensive than what is claimed here).
    I have a Luxman L-210 amp with similar power and about a few years younger. I love the sound of it and I am really curious what you think of it.

      I just bought(2 weeks ago) a total restored AU-4400 here in the Netherlands. From a man who had i think 5 vintage Sansui’s.. Sounds great via Bluesound Node 2i and a pair of Dali Oberon 5 speakers. Spotify and Tidal.
      Years agp i had an AU-317(not restored) and sounded great as well.
      Now i have an AU 515(recapped) and the AU-4400( restored also the exterior); it has a sliver frontplate, not black. The AU-4400 is 20 watt at 8 ohm, the AU-515 12 watt at 8 ohm.
      If i’m right.
      Yes, you can say i’m a Sansui lover.
      An AU-317 i will get later.
      But i prefer a restored(capacitors/transistors) one.

It was the most soulless sound I've ever heard, and like you say it was total silence in the background almost like someone had put the old Dolby switch on (that you would get in tape decks) times 100. That to me, isn't life like, that's synthetic, to me air has a sort of sound sound to it and that should not be removed. I've heard this in some remastered CD's too, all the life blood of the music is removed (the air). Really love your videos, they are so in keeping with the way I describe things too, it's uncanny!
