In 1975 I purchased the AU 7700 with JBL L26 speakers and a Sansui belt drive turntable. That was the cleanest system I ever owned. Not the most powerful but overall best sounding. I wish I still had it.
I have owned my Sansui AU-7700 since 1978. I have the matching tuner the TU-7700 also. My favorite speaker hooked up to it was the Vandersteen 2Ci, at least for sound quality. At 86db per watt they needed more power. I had a set of Speakerlab 4's hooked up to it which used the old style Electrovoice horn tweeter, like the ones used in the older Klipsch speakers. Those would rock out and rattle the house. Those were 93 db per watt. I am working on a Sansui G-8700DB and when it is done we will see which one I like better. Remember more watts doesn't mean it sounds better. That one is 160 watts per channel.
Its sooo different. The Sansui is fun & has tons of vintage character. You know, sweet midrange and great bass. The Sansui is a sit and listen to your favorite 70's rock band type of amp...The Bryston is more refined, tighter - deeper & certainly more powerfull. The problem I found with the Bryston was matching a good preamplifier with it. When I finally did, it made all of the difference!
i think the loudness on this and most sansuis are meant to be played in the on position no matter the volume, you ge tmore body in voals and bass just doesnt go as deep if you just used the bass control knob. My settings with the loudness on bass at 1, mid at 3, treble at 11.
I believe there are a few period pieces that work similar to what you've state. Almost like a variable loudness control, adjusting based on volume. Thanks for sharing!
You should be able to put your hand on it, without burning it ;) I've never checked with a laser thermometer - but, 55C (IMO) is Class A territory & seems hot. It I place a "traditional" thermometer just above it on the lid grill, I'd say about 30C at most. Any hotter may be a indication of the bias set too high. If you have one of these, check and report back!
sansui is my favorite sound. Yamaha NS-690s or 1000's, then put on the jazz or the classical and enjoy.....maybe a touch of eq. no one listens to 100 old school watts only to show off for half a song or so. my sanyo jcx2600k is 85 watts and is more than youd ever need.
IT's a good video, but the balance between your voice and the music makes it difficult to hear what you're saying. And the audio overall is such that I have to boost the volume higher than usual.
Here in Canada, $1000 will get you a AU-999; a couple more hundred - the AU9500...It really all depends on the market - & what someone is willing to pay I guess.

The AU-7700 has a distinct warm sound - I call it Sansui sunshine!
My AU7700 has found it's new home - The new owner just loves it!

I love vintage Sansui with 3 tone control.
Thank you so much for doing this
I just got my AU-7900 serviced and am looking forward to using it again. I see you had a TU 999 under your amp. I grew up with that tuner.
Again, great review! How would you compare the sound quality of this amp versus your Bryston NRB? will you choose one over the other?

Very nice amp! What’s the intro track? Human League?

How hot the heat sink is supposed to get under normal operation and normal/low volume ? My heat sink gets 50 to 55 Celcius (infared thermometer).

most likely dc bias too high and need to adjust down to the service manual.

I just listened to a pair of NS-500Ma, WOW!

Noted!
Thank you ~ I'm not trying to cause trouble.

If the unit is in good condition, the AU 7700 sells for $1000 or more.
Here in Canada, $1000 will get you a AU-999; a couple more hundred - the AU9500...It really all depends on the market - & what someone is willing to pay I guess.
