    Sansui AU717 dropping left channel after rebuild

    Hi All, I restored my all original Au717 last year following Leestereo's guide and parts list. Before doing this, the channel would drop and would only come back on if I quickly turned the volume knob higher. I thought cleaning all the switches and pots along with the rebuild would have fixed...

    Anything that sounds close to Sansui AU-111?

    Sansui AU-111 is becoming a holy grail among vintage and Sansui fans, it is near impossible to find one offered for sale in recent years. Which vintage amps out there that could offer a sound that's near the AU-111? Especially, that illusive "aura" of tube amp? The AU-70? Or any SS amp? Then...

    Sansui SP-2500 Woofer Replacement

    Hey guys... picked up a set of Sansui SP-2500s at the local thrift store today in fantastic condition for $30. One cabinet is in perfect working order, while the other cabinet has a woofer producing absolutely zero output. Tweeters and squakers are functioning beautifully, nothing from the...

    Best Looking Vintage Amps/Tuners/Receivers plus sound rating 1-10

    Hey guys, thought this might be of some interest. I bought an au-666 and tu-666 Sansui combo because it looks amazing and the audio properties sounded fair also. What vintage kit does everyone else find visually beautiful? And how does the sound match? Do receivers look better than...

    Sansui G4700 output transistor replacement

    The original output transistors 2SA1102 / 2SC2577 for the G4700 are essentially unavailable. Would the 2SA1693 / 2SC4466 or the 2SA1492 / 2SC3856 be good replacements? The 2SA1492 / 2SC3856 might be overkill, but could they be more resilient? Or would they not work at all? Transister Combo...

    Sansui SR 838 Turntable Owners - Do you want a 'Subweight'?

    Do you need a Sansui SR-838 "Subweight"? If you are running a heavy-ish cart which weighs ~10 grams or more, this near-impossible-to-find accessory is required to properly balance the tone arm. I am going to have one/some made, as I now have specs for the part, and have sent them to a tool &...

    Rotel 991? Opinions?

    What's up folks? I've got a chance to buy a Rotel RB 991 (200 wpc) for $395. Anyone have any experience or opinions about this amp? I currently have a Marantz 2230 and a Sansui 881 and would most likely use one of those as a preamp to the Rotel to drive some Infinity CS-3008'S. There's also a...

    Sansui AU-111 restoration

    Hello I have a new project on the workbench :). It is a nice Sansui AU-111. The amp works, it has new output tubes, but it needs some attention. The idea is: - Change all the electrolytic capacitors, they are still the original ones. - Also change the mica ones, as suggested by @smurfer77 in...

    Hum Troubleshooting Sansui 9090DB

    I have a nice Sansui 9090DB I'm troubleshooting for a friend. It has a quite discernible hum in both channels. It had been thoroughly recapped when he bought it, but not main filter caps. They used good caps too and were quite thorough in that regard. I decided to replace the main filter caps...

    I just woke up

    Hello everyone, new to the site but not new to audio. Back in 78, I fell in love with audio, specifically the art of reproducing sound as it was intended. I purchased my Au-Tu 717's new, added some Klipsch speakers, B&O turntable, and I began my journey. Speakers came and went, amps were...

    Sansui JDP adventure part 2: Sansui AU-D907 Limited

    I decided it was good advice from joseHH to keep this amplifier model in a separate thread. This is the first of two AU-D907 Limited that I bought. I have another one on the way will arrive somewhere in the next 2-6 weeks. My plan is to keep one as original as possible and upgrade one as much as...

    Attached are two photos of different Sansui SM-320M receivers (well, maybe). Photo 1 was lifted from another AK thread. Printed on the front just under the center of the dial glass is the word “Sansui”. There are other photos floating around that would seem to confirm this being a (genuine)...

    Less efficient speakers on AU 20000?

    I have a totally restored AU 20000 (The resto cost a fortune) and I was wondering if it could handle a more demanding speaker. Should there be a problem running ProAc Response 3.8s? Please look at the graph below pertaining to my 3,8s.I just don't want to kill my recently restored Sansui.
