Sansui B-2101 Power Amplifier Restored, New Electrolytic Capacitors, Warranty And More. The 2 main power amps have all new capacitors on them and all new transistors also all the resistors were checked for value and a lot were replaced, new thermal pads were installed on all transistors needing them all the electrolytic capacitors and main filter caps on this entire unit were replaced, all the \"Black Flag\" troublesome caps were taken out and replaced with a better non flammable high temp ceramic type, new audio grade Elna SilmicII and Nichicon Fine Gold audio capacitors filter the main amps the 4 main filter caps were replaced with new United Chemi-Con 10000uf capacitors and in the power supply with Nichicon 105 degree low impedance capacitors and 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 good cosmetic condition all the display lights work as should a new LED was installed for faceplate illumination and Banana Plug Binding posts were added for channel A speaker connection, the faceplate is in good condition it does have some small marks on it but not to noticeable the top and sides are in good condition there are some light surface scratches and marks on the cover the pictures show them well there is also a picture of the unit with the C-2101 preamp, that is being sold separately. With the recap and the new output transistors this sounds absolutely incredible!!! and I am sure better than it originally sounded when it was new. This model was made in 1984 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 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 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.
