Question about Audio Players & Recorders

1 Answer

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??

regards
Graeme

If the speaker protection is activated then this would indicate that either a dc voltage is appearing across the speakers or a short circuit on one or more speaker cables. Since you are able to get normal sound through the headphone function the former is less likely and you should check for a possible shorting speaker cable. Another possible cause for the symptoms can be dry joints on the speaker protection relays.

My NAD C320 outputs a very low sound volume


Hi there I have a C340 that has similar problem, you must have bought this from ebay, lol.

Nad made a mistake on the C range, the pre - power link can be shorted out. if the pre is shorted out it takes out the pre amplifier stage, I have managed to get the right channel working, I will keep you informed what is the cause of the left channel. I have replaced the pre-amp IC and a couple of Jfets and transistors. Once I have repaired the Amp I could repaire yours if you like???

Hey i have a sony amp (600 watt xm-zr604) with 2 10"sub(sony xplod).when i raise the volume hight enough the amp go off(red light came on) what can i try


sounds as though (at high volumes) the amp thinks it has a short circuit. This may be caused by the way you have them connected.
Speakers have a resistance and amps needs a certain amount of resistance to function right (too little resistance = short circuit)
The way it works out for the speakers is, if the two are connected to one amp output channel, the amp will see half of the resistance of a single sub. (4 Ohms/sub amp sees 2 Ohms)
If the amp instructions say that it's 4 Ohms/channel then you need to use 1 channel for each sub.
Hope this has been some help.

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 AU-717 amplifier with a bad volume control. How do I find either a replacement or someone who can repair it?


A replacement control will be difficult to locate as it is long out of standard service time. That being said, it is also rather rare for a control to fail completely. Can you please indicate why you feel the volume control is defective? Perhaps there is another problem that will be easier to repair.

Thanks,
Dan

I need a replacement volume control for a Sansui-AU-717.


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

I am more than happy to answer any other questions you may have about it, just give me a hoy :) If you are still unsure, or have problems, then before you give a rating for this advice, please get back to me and we can try some more things.
Thanks for using FixYa, If you consider the advice I have given you as sound, a FixYa rating is a great reward for my efforts to help you. Cheers.

possible short in speaker system. Disconnect the speaker to that channel. if it does not click off then you have a short outside the amp in your wiring or in the speaker.
