    Sansui AU-717, TU-717, SC-3110, GX-5 rack value?

    Local guy has this setup for sale, all in working condition: Sansui AU-717, TU-717, SC-3110. He's asking $1,100. I believe the price includes a GX-5 rack and rack handles for all components. I know he put some work into fixing the 717 and getting the 3110 working correctly. Tuner has been...

    Sansui AU-717 restoration - no sound and it's FILTHY!

    This is a recent project I started. I've done quite a few AU-717s, but I wanted to take a different approach this time. Starting with the power supply, I de-soldered all of the wires to allow me to easily remove the board to work on it. I (almost) completely disassembled the unit in order to...

    Migrating from AU717 to BA-F1 combo

    Hi Folks, First of all, I want to thank you for the possibility of joining this prestigious forum. For about 15 years, I have had a Sansui AU 717 amplifier powering Bose 901 series 4 speakers. Very happy with my team but always wanting a little more definition and power for those hungry 901s...

    Hi my electronic knowledge is behind most on this site so I will try and get straight to the point. Ive just recapped a 717. It works but has excessive hum on inputs like Aux / Tuner when unconnected . When you short the input or attach a CD Player the hum goes away 100% but something is not...

    AU-717 regulated PSU voltages

    Every now and again we have someone asking questions about weird regulated PSU voltages for an AU-717 during restoration i.e. with the Driver Modules removed or other boards unplugged. The reason for this is that with the Driver Modules installed they complete a ground path for the whole...

    Please recommend someone for Au-717 restoration

    Hello! I have an AU-717 and TU-717 (not sure what to do with the receiver). I am looking for someone with a good reputation to restore my amp. Some of the names I have found appear to be in quite old threads, or out of business, or don't specialize in Sansui. One candidate (name withheld) looks...

    JBL L-96 or new equivalent speakers?

    Hey there!, I actually own a pair of L-50s which I love but since a while I'm searching L-96s but here in Germany are pretty difficult to find.. I found an ad where they are being sold for 850eur, with a small hole in one of the mid-tone cones, they seems to be in good shape they seem to have...

    New Sansui fan here!

    Hello all, Just bought my first Sansui gear AU-717 and came across this forum. Tons of info here so it will take a while to catch up LOL. I'm looking to do a complete recap on the unit who do you recommend, technician, to do this work? Any help is greatly appreciated. djfrankie21

    AU-717 No signal on right channel

    Hoping the experts here can point me in the right direction (I have scoured AK for clues, but so far no luck) I am working on a 717 for a friend which has a dead quiet right channel. I have cleaned all switches including the back couple/separate switch. There is no signal at the right side...

    AU-717 Total Rebuild/Rack Refurbished

    I received my fully restored AU-717 from Leo at Precision Audio Restorations on Saturday. I’m the original owner of this marvelous amp. The volume control was stiff and the left channel was silent. I sent it off to Leo based on recommendations from this site. Leo did an absolutely excellent job...

    AU-717 rebuild recommendations

    Good Afternoon. I am looking for recommendations on a rebuild/restore service for my AU-717 amp. I bought this system when I was in the Air Force back in the late 70’s. I did a short tour in Korea and like a lot of other service guys back then, we all got big stereos for our rooms. I picked up...

    Volume pot cleaning guide for AU-717

    This week I was wrapping up an AU-717 overhaul and noticed the volume pot was noisy around the 9 o'clock region. My first attempt and fixing it was to turn off the amp and work the pot back and forth through the full range a couple dozen times. This didn't help so I knew I needed to do something...

    Leestereo's Restoration & Upgrade of a Sansui AU-517

    AK member @McDee56's very nice Sansui AU-517 integrated amplifier received a complete restoration and upgrade. Note that due to the shared topology between the AU-517 and the AU-717, this current restoration/upgrade is very similar to the latter's detailed AK thread. Part 1: Tone Control...

    AU-717 Power supply board re-capped, now no V from tranformers

    Hi all, I hope someone can assist with some trouble shooting suggestions. I have been working through my AU-717, which was not working when I received it. I renewed the majority of capacitors on the Power supply & protector circuit board (F-2663) per some other information on this forum. I...

    Project: Sansui AU-717 (Restore / Rebuild)

    In the quest of vintage stereo, my adventure continues. Last weekend I found the Thanksgiving project. A non-working unit popped up, and I snagged it. The unit was a non-working sister to an AU-717 operational unit sitting at member @MtnBeachBum. Chris definitely was a AU-717 fan...

    Sansui Au-717 - repair help: recap of Board F2721 and protection issue

    I have a Sansui AU-717. Due to age and concerns over glue, I have undertaken a recap. Prior to recap, the unit worked. It did take awhile to power on (~10 sec) but was otherwise in good working condition. I started the recap with board F2721 and this is the only board I have touched so far...

    My first ever restauration of my good old Sansui AU-717.

    I’m the first owner of an 40 year old AU-717. I’ve enjoyed my Sansui for years until it started switching off and on. It was sent to a “Sansui repair shop”. Funny though: after switching it on, it worked but the little red led kept on blinking. A few years later, it started to hum. A friend knew...

    Sansui AU-517/717 Headphone Jack (Non-standard)

    Does anyone have a source for the headphone jack used on the AU-517/717? It is not the common type with a threaded collar, but rather it is attached via a 2-screw bracket.

    Repair technician recommendation in NorCal

    Hello everybody, I have spent some time going through the threads but haven't found any reference to a good Sansui repair shop in Northern California. Does anyone on here have a suggestion? I have a Au 717 that has a channel out, and I think needs a pretty extensive recap and refresh. My local...

    Sansui AU-717 restoration service recommendation

    Hi all, I am a bit of a newbie on this. I have an AU-717 that looks like it needs some restoration work. For one it appears that a previous owner fused the board that separates the preamp from the amp. The switch on the back does nothing and when I opened up the unit it appears that parts of...

    I've been a very happy AU-717 owner for the past 13 years (thank you, AK forums, for that excellent recommendation). I've recently started to detect an audible hum through my speakers whenever the amp is powered on, even with the volume pot all the way down. Changing sources doesn't change...

Pictures looked fine so I sent an offer (250€) and the seller accepted. Lucky me. I read so much about AU-717...
