Sansui AU-717


The AU-717 amplifier incorporates an advanced design feature which has extremely low inherent transient intermodulation distortion enabling negative feedback (necessary in traditional amplifier design but undesirable) to be reduced to the absolute minimum.

Power amplifier design too, shows a departure from tradition resulting in the elimination of DC drift.

Differential push/pull amplifier stage eliminates open-loop distortion. The driver stage is 3-stage darlington connected.

Channel separation: 60dB (MM), 65dB (line)

re: AU-717

My dad has a Sansui AU 717 Amplifier and he was just wondering if there was any place that still does repairs on the product? I tried looking on the internet but I did not have any luck, though I did find this question and answer site. I hope you can help me out.
Thank you for your time.

re: AU-717

Dallas Vintage Audio in Bedford Texas can repair your Sansui AU 717.
You will have to look them up on the internet, I don't have the address or phone number handy.
They are closed on Thursdays and Sundays.

re: AU-717

is there a way to hook up a JBL DS - 10 SUBWOOFER TO THIS AMP ?

connection to an onkyo high currant ampifier

i currantly have an ONKYO AV RIECIEVER HIGH CURRANT AMP. we noticed it does not have a place for a phono jack for hooking up a turntable. my husband purchased an older model sunsui integrated amplifierAU 717 and i was wondering if it is possible to hook this into our amp or if it is going to cause a problem with compatibility?

You will have to spend a lot

You will have to spend a lot of money to get a better RIAA stage for moving magnet cartridges than the one in the Sansui AU-717. I have tried several and none was better.

Connect the pre-amp out terminals at the back of the AU-717 to the auxiliary, CD or tape input of the Onkyo. Switch the AU-717 selector on the back of the amplifier to separated, and plug the turntable into the phono input of the AU-717.



re: You will have to spend a lot

THANK YOU for this information..

Turntable to Onkyo

Get a separate RIAA stage instead. There are several makes around, here in Sweden NAD is available with models PP-2 and PP375, Cambridge has one, I think Denon also have it.
