Sansui AU-919 Amplifier Restored, New Electrolytic Capacitors, Warranty And More. The unit has all new capacitors on them all the \"Black Flag\" troublesome caps were taken out and replaced with a better non flammable high temp ceramic type, all the transistors were checked and replaced if needed the original output transistors were checked and left in because of their high frequency design for sound also all the resistors were checked for value and were replaced if needed along with all other components, new speaker relay was installed, new thermal pads were installed on all transistors needing them all the electrolytic capacitors and main filter caps on this entire unit were replaced with Audio grade capacitors, new audio grade Elna SilmicII audio capacitors filter the main amps the 4 main filter caps were replaced with new Nichicon KG and Super ThroughAudio capacitors and in the secondary power supply with Elna Silmic II and Nichicon FG audio capacitors, 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 very good to excellent cosmetic condition it has rack handles and rear bumpers installed all the display lights work as should, the faceplate is in very good to excellent condition the top and sides are in very good condition there are some light surface marks on the cover the pictures show them well. With the recap this sounds absolutely incredible!!!! and I am sure better than it originally sounded when it was new this is by far Sansui,s best sounding integrated amplifier and it is from my personal collection. This model was made in 1978 and designed for USA and International use it has multiple voltage settings for all countries. 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 55 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 3 month warranty for repair, I rebuild Sansui amps I will also trade or buy your non working Sansui unit if interested please email me.
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 ! All the best.
