    Sansui AU-317 turns on but no sound

    A few weeks ago I bought this AU-317 MK 1off eBay however when it arrived there was no sound coming out of it. Went back and forth with the seller and ended up keeping it at a significant discount. I've checked all of the audio inputs (AUX and Tuner) and channel outputs with no success of...

    Hello everyone, First of all, thanks everyone for all this knowledge shared in this forum. I am restoring a Sansui 9090 early production that was not working. It had plenty of issues that I had to fix (some output transistors failed, driver board, protection, service bulletin not applied)...

    Talk me out of a 8080 or 9090 please :-)

    Ok, so I've been thinking about getting an 8080 or 9090 (or hopefully a 990) but I'm also wondering if I really need to... my current receivers are: Mac 4100 (mint in condition and functionality) - 1/2 of main system. Sansui 5000x (slight crackling on power up sometimes, otherwise good) - in...

    SP-70 Dead Tweeters

    I've picked up a pair of Sansui SP-70 in excellent condition but both tweeters don't work. I've measured them seperated from the crossovers and i'm getting OL, even disconnected the woofer to see if the tweeter would play and no go :(. Any suggestions on a good replacement that I can use in the...

    Sansui 7070 Speaker Select switch replacement

    I have a spare Sansui 7070 I ordered from eBay quite a number of years ago. When it arrived the speaker selector switch was badly bent. UPS Insurance reimbursed the cost so it was free. After it sitting in the basement for 8 years or so I dug it out and fired it up yesterday and it works and...

    Speakers making static popping sound even when volume off.

    Hi there, I’m a total novice when it comes to old speaker equipment. My current setup is a sansui7000 with two sp3500 plugged into along with a record player. Intermittently over the years occasional static comes through, but usually rearranging power cords, wifi routers, Alexa’s, or replacing...

    Hi all and thank you in advance. I have a beautiful Sansui G-5700 that I had professional restored 8 or so years back. The past 2-3 years it wasn’t getting much use. It was being safely stored at a family members house after I moved abroad temporarily. Recently, I moved back locally and have...

    Sansui Seven Tuner Power Supply

    Hello everyone, I was listening to FM on my Sansui Seven, it suddenly went mute. Upon investigation, it happened to be TR002 on the power supply board which is a 2SD330. This supplies +12v to the Tuner section. The rest of the unit works fine. Many in the forum mentioned TIP31C or TIP41C as a...

    Sansui 350a input interference question

    On my Sansui 350a, I only had an input connected to the aux ports, but accidently left the selector on phono. When I started to play music, I could hear the aux input, very faintly and noisily. Selecting aux played my input like normal. Is this just harmless, but interesting, interference? I...

    Hello From Morocco, Tangier

    Sansui BA-2000 Bias Adjustment Q/A

    Can't find that warm sound I want.

    I stayed in an airbnb a while back with a pretty basic marantz amp and table(not sure which) and some advent speakers. The sound I heard out of that system was magical to me, like a warm hug for my ear holes. After that I had to build my own system. I posted a few questions on Audio Karma, did a...

    Sansui QRX-9001 no sound in rear left channel

    Sansui turntable specs, the deck or the cartridge?

    Hi All, Are the reported SNR specs of 70s Sansui TTs driven by the cartridges or the decks? Would a modern(ish) cartridge help, or was the motor tech and understanding of damping of the day the limiting factor? I've always wanted a Sansui TT to pair with my Sansui amps and receivers. I'm...

    Fuse Resistor Primer 101

    Hi All, I, like many it appears, can be confused by the Fuse Resistors (FR) used in the Sansui vintage amps of the late '70s. The Sansui 9090db I am currently working on has a few on the Driver Bd and Power Supply Bds: .33 ohm, 1 ohm, 4.7 ohm, 10 ohm, 150 ohm, 180 ohm, 330 ohm. First...

    Sansui 517 tuner and tape inputs louder than aux for the same device.

    See title. Is this normal ? And if not is it easy to solve? I would prefer keeping it as is as it was completely overhauled a few years ago. But since it's not mine I don't know if this has always been the case.
