Default Sansui AU7900 Integradted Amplifier

Hi.

I just got my hands on an older Sansui AU7900 Integrated Amplifier.
I've read so far that this is an amazingly good sounding amp. I wouldn't know it first hand 'cause mine doesn't work.
Does anyone have the schematics for this amp on hand or knows of a page/link where I can get them?

Thanks in advance,

PhantomBox

I'll email you the service manual. I found a beautiful AU-6900 in the trash at work recently, so I searched and found the documentation. It covers the AU-5900, 6900 and 7900.

I just re-adjusted the bias on mine the other day. One of my Favorite amps of all time! (Their tuners were awesome too. -I'm a big Sansui fan.)

Hi Todd.
Thanks for wanting to send them, but it seems that you actually forgot to include the link in your reply.

And hi "rtirion" and "destroyer".
There are links in your replies but it apparently is scanned in a low resolution and it's going to be a hard time to read the actual "small printing".

@ Todd

Hello Todd!

I would be glad if you could also send a service manual to me too, or could you put in a link in this topic, please?

reg. Michael

Some fantastic Sansui's here.

Anyone remember the AU101 - this was a small 10 or 12 watt per channel amp - sort of a 'starter' integrated.

They sold loads of them during the 70's.

Hi,

Sorry, I've been a bit out of touch lately. The service manual I have is the same one that is provided in the 2 links above. In fact I believe I originally grabbed it from the second link and sent it to Jan for his website (the first link.)

..Todd
