AU-G99X

Don't forget to adjust the power meters. They do have a trimmer and a procedure to do so. It must be in the adjustment procedures on the sm.
Enjoy.
 
Another learning experience for me are the adjustment's on this thing (very tedious)but after about an hour of trying to get everything right I zeroed the DC offset and set bias nuts on 20mv.Now I have Alvin Lee's the last show playing and it sounds pretty darn good.View attachment 769552

Also check your scale light. Looks like its out? I think its a 8V lamp from memory.
 
Should look like this. Once you have taken the front face off, the lamp is on the far left side near the power switch. Its a soldered type lamp. Remove the assy to access it. Can be little tricky.

I'm always on the lookout for sansui gear but I haven't ever bought anything newer than 1980 and I ran across this deal today.
1 sansui AU-G99X
1 sansui TU-77X Tuner
1 sansui RG-710 Equalizer
All for $250
Can anyone tell me if this is a good price and what year this setup was made?
I have an AU-G99X and use it every day. It seems to be a great sounding amp. I bought it when I lived abroad in The Philippines around 1990, I think, and when I returned home to Canada I posted to one of the Facebook groups (which shall be nameless) asking their opinion of this unit . I was told in no uncertain terms that it was BPC--black plastic crap. I also posted the same query on Audiokarma and was told it was a world class amp. So which is it? I am still not sure what to believe. I find it a most enjoyable piece of audio equipment??!?

It's most definitely NOT BPC - whilst the build quality isn't as good as some Sansuis, it's a very robust amp and offers very good sound quality indeed.

There are some real snobs out there in audio land who think that anything post 1980 is rubbish. More fool them - they are missing out on the best that many brands (Sansui included!) had to offer in terms of sound quality.

This deserves to be quoted, because it is absolutely correct in my opinion.

Yes that is what I believe also. I use my AU-G99X in a sound system consisting of Mirage OM10 front speakers, JBL 2600 rears, M&K Sub woofer, Signet centre channel, Marantz TT400 for vinyl LPs. Most enjoyable sound system for my requirements. Many thanks for all your responses.
 
I have one as well and will vouch for it being a deceivingly good amp. Yes, it has that 80's look, and is not quite the beast a BA-3000 is in terms of build quality or weight (not that it isn't heavy, mind you). However, under the hood, it stacks up to the best of anything Sansui made, short of the later Alpha series amps which I consider to be a higher tier of amp, as they were really going for esoteric high end specs by that point.

In short, if you find one that is 3 bills or less, I'd say it's a very good value. Can be mated with a TU-D99x tuner, an SE-88 or 99 EQ (if so inclined) and an XP-99 turntable. A CD-X701i cd player will aesthetically match that stack as well for a complete setup, assuming you can find one.

I agree with Rob and Sansuiman, the AU-G99x is a good sounding amp. I just took mine out of rotation and it was driving my NS-1000’s. I haven’t done a side by side but to me it has a similar sound to my C-2101/B-2101 pre/main combo.

Cheers,

The G99X is an underrated amplifier that followed the much esteemed D11II. It is an early X balanced amplifier and, while it has the what we now consider a funky display and a less impressive build when compared to an AU 919, it is by no means an inferior amplifier in sound quality. Those who don’t like the display can turn it off. I don’t believe that there was any regression in sound quality as the TOTL Sansuis evolved. No apologies needed for this one and it is still quite the bargain. If I were to choose, I would go for this over the D11II. As I recall, and those in the know please correct me if I am wrong, the D11II still had black flag capacitors, the G99X did not. Also the D11II is difficult to work on as it kind of flops apart on the bench, the G99X is more robust. I can vouch for its sound quality but my memory may be failing me as far as its innards.

My example didn't have any, but interestingly we have threads running for 2 AU-D9's (my thread, and another), where one AU-D9 has the Black Flags and the other one (the one I am working on) does not. The Black Flag positions in the one I am reconditioning are all occupied with 'Noble' polystyrenes, I believe this was done by Sansui before it left their factory. :thumbsup:

Thanks Hyperion

I appreciate the correction. I did some research, which I should have done earlier before posting, and can find no mention of black flag capacitors and the D11 II or subsequent amps. At least some D9 and D11 amplifiers had black caps, and I quote you for the D11:

https://audiokarma.org/forums/index.php?threads/sansui-au-d11-blows-outputs.864812/

Does the amp carry any "black flag" cap?

Yes it does, good point Karl, there are some on at least 3 of the PCB's, the Tone Control Amp, The EQ, and the Driver Amp all have some, there may be more.
Identified in the SM as "125V PC" - meaning 'Polystyrene Capacitor'

But this is not germane to this current discussion.
