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.


Power output: 85 watts per channel into 8Ω (stereo)

Frequency response: 20Hz to 20kHz

Total harmonic distortion: 0.025%

Damping factor: 60

Input sensitivity: 2.5mV (MM), 150mV (line)

Signal to noise ratio: 78dB (MM), 100dB (line)

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

Output: 150mV (line), 1V (Pre out)

Speaker load impedance: 8Ω (minimum)

Dimensions: 430 x 168 x 389mm

Weight: 17.8kg

Year: 1978

Really hard to find a weakness with this amp . Awesome build quality , great soundstage , plenty of power , hard hitting bass , musicality is very high . I can listen to this amp for hours with minimal fatigue . Fairly expensive on the used market but absolutely worth the money but when serviced should last forever . If you get one hang onto it because clean fully functional units will become harder to find . One of the best integrated amps ever made imo . Buy one when you get the chance and see for yourself .

Have an AU 717 with phono issues.
Love the amp, but the left channel
is weak and distorted in the phono
stage only. Appears in both phono inputs.
Any suggestions on what I'm into with this?

re: AU-717

Does anyone know if Phono 2 amplification is for LOMC cartridges.

re: AU-717

The phono inputs are the same, moving magnet only.

re: AU-717

Found one at the flea market for 65 $ needs some fixing. but i can see right of the bat that its a good one it has four 15000uf caps the same as my Phillips that is 210w per channel and consumes the same amount of watts at max 700watts and this one is only 85w per channel. Cant wait to get it running and have a listen :)

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.
