Hi p00pmeister

This great old amp uses an Alps brand attenuator. This could be a little hard to find an exact fit replacemernt. Have you tried to clean the control. The can generally be restored by flooding the internals with CRC 2-26. If you have intermittent channels, check also the amp/preamp switch to the rear of the amp also.

Check out this Has some instruction on dealing with the disassembly of the attenuator

Off of the top of your head could you tell me what my problem with my sansui AU-717 amps problem could possibly be? When I am playing a cd if the volume is even barely loud the sound will go out then I...


It sounds like one of the following:
> You have an impedance miss-match between your speakers and the amp (speakers have am Ohm rating lower than the amp can handle),
> You have the switch set to both A&B speakers turned on, but have speakers connected to either the A or B set, but not both, or
> You have both A & B (4 speakers) connected, and one or both have an Ohm rating lower than 8 (if two sets are connected, they must be 8 or higher).

My best guess off the top of my head.

I have a Sansui 717 Receiver/Amplifier. Everytime I turn on the power it will warm up for a few seconds...the blinking will stop and ready. I try to turn the volume up and it cuts out immediately. Can this...


Generally speaking, an amp protects itself from heat, shorts and overloads.


Overloads can be from excessive periods of high output and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced hands-on tech.

I have a sansui G9700 receiver/amp. The volume control works intermitantly. Must play with it to get volume. I believe I need to replace the potentiometer F3085. where can I get one? Erick G


The potentiometer doesn't need to be replace, it has collected dust inside causing the intermittent operation. Buy a contact cleaner/conditioner to spray inside it and move the potentiometer clockwise and counter clockwise a few times until the dust inside it is gone.
Check this link to find a contact/conditioner cleaner or you can try spraying rubbing alcohol but this could because alcohol doesn't not lubricants properties.
Let me know if you require further assistance.

I own a classic Sansui intergrated amplifier (AU-717). It has a short in one channel. At low volume, the sound shorts out. I've had this unit for about 20 years now. Otherwise, it's a great product!


Hi mellemcee


Cool amp mate, and becoming collectable now to. Sansui amps from the era where the best in the world of HiFi. iT may have lost bias control to the offending channel, it may have dirty source switches, tape monitor switch, or even speaker switching. The speaker protection relay may also have a dirty contact, will usually burst back into life with a quick rotation of the vol control. Can you pin the problem down a little more with the info i have given you, try all the controls to see if it impacts on operations, you will need to fix those problems first. Low bias would make that channel sound distorted at low levels also. Is this what is happening to you??

I NEED TO KNOW IF THE CA2000 PRE AMP HAS THAT CLICK TO LET YOU KNOW IT'S POWERED. AND HOW TO CONNECT IT TO THE AU-717 AMP


Typically pre-amps do not have a relay. Any muting that is done is done using transistors.

Try rick at stereomanuals.com
The shutdown would be from a voltage supply in the power amp seeing too heavy a load and "shutting down" so that the amp doesnt Fry
