    2 more Sansui AU-X1 for restoration

    Next month, I will receive 2 Sansui AU-X1 for restoration: the first one, the vendor said, is not powering on, and the second, the vendor states that it is smoking. Well, it is going to be a challenge, but I can touch them after the middle of October. I will need to send both of them to Power...

    Sansui G-8700DB stuck in protection / relays not engaging — looking for help with F-3072/F-3073 power/protection circuit

    First off let me apologize if this isn't the right place for this but I’m working on a Sansui G-8700DB that has turned into a fairly deep protection/power-supply troubleshooting job. I’m hoping someone familiar with this model, or with Sansui’s HA12002 protection circuit, may recognize what I’m...

    Sansui squawker trade out

    Hi all, I have a bad S-106 “high squawker” in a Sansui SP-3500. It’s 12ohm 40watts, which I’m sure many of you know is an oddball to replace. If I am unable to locate an S-106, I am considering trying to physically adapt a Sansui tweeter of the same impedance and watt rating to stand in until I...

    SC-3100 stopped, won't start, belts look good?

    Howdy, my SC-3100 cassette deck just stopped one day and when I push play or any of the other buttons it just clicks off. Visual inspection shows the belts all intact and I'm just curious if there's something that I can look for? Thanks for any help. Jackson

    I just received a nice Sansui AU-719 for restoration

    I have previously restored a Sansui AU-717 and a AU-919 and both went well. I must really enjoy removing the notorious Sansui glue because I just purchased an AU-719 from a gentleman in Canada. It looks clean and appears to be all original. It powered up normally and came out of protection. I...

    Sansui Solid State Amplifiers and Low Freq. Oscillation

    Hey all, I have a weird issue that's come up twice now, both Sansui solid state receivers, both the same kind of issue, low frequency oscillation. First - I have a Solid State 3500. The outputs are original - as are all pre-drivers/tx on both amp boards. Bias adjusts fine on both channels...

    Model 500A with strange date

    In Friday I got Sansui 500A from Japan. From the information available on the web, it follows that they were produced in 1967-1969, but in this one all the Elco-caps have a date of 1975-1976, I am 100% sure that no one has ever touched this receiver with a soldering iron. Unfortunately, there is...

    Sansui AU 819 vs Sansui AU X711

    Dear friends, some time ago I decided to upgrade my Sansui AU-717 amplifier to an AU-819. The decision was mainly due to the clarity of the sound thanks to DD-DC technology, but the unit I was looking at sold before I had the money, and I was disappointed... As you know, the 819 is a rare piece...

    Sansui Mystery Midrange!
