Item History & Price
| Reference Number: Avaluer:17890906 | Model: AU-717 |

Sansui AU-717 Amplifier Restored, New Electrolytic Capacitors, Warranty In Excellent Condition. The unit has all new electrolytic capacitors, the preamp also has all new transistors and diodes, new audio grade Elna SilmicII audio capacitors filter the main amps, the preamp and the phono preamp, the 4 main filter caps were replaced with new "Cornell Dubilier" high temp capacitors, they have new Polypropylene Film caps added, in the secondary power supply with Nichicon high temp ca...pacitors, new thermal pads were installed on all transistors needing them, this has a new Omron relay and six new main amp board trimmers, I also relocate the two 2 watt resistors from the main amp boards these get very hot and damage them main filter caps moving them solves the main problem these units had also all the resistors were checked for value and were replaced if needed along with all other components, all the old glue has been removed and cleaned off, all the controls were cleaned with Deoxit and work excellent, the bias has been set to the original factory mV settings.
The unit is in excellent cosmetic condition all the display lights work as should, the faceplate is in excellent condition the cover top and sides are in excellent condition there three small marks on the cover top but very hard to see. With the recap this sounds absolutely incredible!!!! and I am sure better than it originally sounded this is one of Sansui, s best sounding integrated amplifiers, this model was made in 1978 and designed for USA use and Canada for 120 volts only. Elna Silmic II capacitors have a 100 hour break in period I have run the unit for about 20 hours for testing so that means that every time you listen to this up to that 100 hour period it will keep sounding better so if you notice a difference in sound each time you turn it on that is why. This is very heavy about 50 pounds so the unit will be packed well. You will have to be home to sign for this or the delivery service will not leave it!! This unit has a 6 month warranty for repair. I rebuild Sansui amps I will also trade or buy your non working Sansui unit if interested please email me. If you want rack handles installed on this they are $60 more and with rack handles and the rear bumpers installed the cost is $80 more for both, just email me if you are interested in these. Please do not be fooled, there are a lot of units listed as serviced and professionally restored the case might of just been polished and maybe the potentiometers cleaned, and some have the capacitors replaced but not the main filter caps well they are just as old and are bad, electrolytic capacitors have a life of about 35 years any 70's or before and even 80's unit have capacitors that could go bad at any time if you are going to spend money on a older unit make sure ALL, including the large main filter caps, the electrolytic capacitors have been replaced or you could be wasting your money and make sure it has some sort of warranty!!
Thank You

Hi there.
The Sansui AU-717 arrived in Singapore last Thursday. I have been playing it ever since. Thanks for a superb job refurbishing the insides of the amp. Looked near mint and smelled like it was straight out of the factory in 1977! It was everything I read about it and more. Not only was it tube like in sound but put out loads of power it is by far one of the best sounding amps I ever heard! I have not turned the volume much beyond the 8 o clock position. So I really did not mind paying your slightly higher price on eBay! All the best.
