I recently picked up an A-9 DC Servo Amp. Any idea what year it was produced? List Price? Top of the line or bottom of the line? Is it worth building a system around? Any help will be greatly appreciated.

Hi Paul

A-9 is manufactured around 1981 and belongs to a series, sorry to say, which isn't representative for Sansui. It can be used for easy listening. You should instead search for amps beginning with AU-????. They are popular models especially AU-9900, AU-9900A, AU-517, AU-717, AU-919 to mention a few of those with higher power. Even those with less power sounds very good as AU-117, AU-217, AU-317 as well as AU-117II, AU217II and AU-317II and there are more.

Let us know what you find.

I'm looking for an A-9 Sansui amplifier.  We have a vintage system that works great, except the amplifier has quit working. 
Is there a good substitute for it?  It is 240 watts.

 

Thanks

There is actually an A-9 on Ebay at this time (auction # 9737245218) if you are really interested to get it. Its a decent amp, but Sansui's AU models are much better, for example, I would highly recommend an AU-717.

 

The 240W is not really the "true" wattage. For the A-9, its rms average rating is 65 Watts. Sansui also made the smaller A-7 and A-5 at the time (very early 1980's).

I picked up an A-80 yesterday (of which i can find no reference on this site, i'm wondering if it is UK only?) - I beleive it is a similar line to the A-9 etc, in any case it is late 70s early 80s i think. unfortunatley somone had removed the serial number which would be the ideal dating method so i read.
anyway, i bought it to stand in for my other amp while it is being repaired, and i must say im impressed so far.  My only other experience of Sansui is hearing my friend's one - which i think was the better mid 70s AU series. 

I found the bass on the A-80 to be good, firm, and not 'fluffy' as it so often can be on older transistor amps. The midrange is very nice indeed and not at all harsh.  It is treble shy in my opinion, but you get used to that. It is remarkably quiet on all inputs, incl. the phono.  it even has the option for MM and MC cartridge, which doesn't seem to me to be an indication of a company cutting costs drastically!
it has a good 'grip' on the speakers (bookshelf type), good seperation and basically a pleasant listenability.
In my opinion , £20 GB well spent.

Hi Jim
A-80 was manufactured 1980 and A-9 1981. It was the first amp together with A-40 and A-60 in SuperCompu Series. In the series the receivers R-30, R-50 and R-70 were included. If you like to know more you can go here and click on any category. In the next menu do a search for A80 and see whats available.

I have always like to hear SANSUI in those days of 70's and 80's.
Now I am searching for AU-717 in good working condition. Can anybody help ? Actually I found an old AU-6600 in a shop in my area but when I searched in Internet, no mention of that model.

 thank you,
Keeper

Hello Antak,

With AU-6600, you can't go wrong! I think (,but this is of course personal,) the AU-XX00 (5500, 6600 & 7700) is the nicest series Sansui ever produced! I have almost everything from '70 to '80, starting with AU-777 & AU-7500 over AU-717 up to AU-D9 & AU-X1. If my house were on fire, and I could save one of them, it would certainly be the AU-7700! It looks and performs similarly to the AU-X900 range, but the knobs look and feel (in my opinion) nicer.
