One of the finest sounding receivers ever built. Power to spare. Great FM section, and one of the best units for vinyl. I sold a Mac unit to get this, and have never regretted it.

Recently swapped my audio dead Panasonic 9XX, do everything receiver for a Sansui 9090 plus some cash. Found it in old shop here in New Mexico. Seems in perfect condition and sounds really good. Already owned a Sansui 2000A from 70's Audio/Photo Club in Germany. Was looking for documentation on the 9090. Have docs on 2000A, if anyone needs a copy. First time on site and from reviews and replies, it's a great find. The previous owner has RCS type cables in place of the Pre-Amp jumpers - guess that's ok, right? Downloaded the user's and service manuals, thanks very much. Will learn all the toggles and knobs functionality. Thanks. jn

WHAT A WONDERFUL AUDIO WORLD OUT THERE - thanks to all you hifiengine.com Ame-goes. Pardon me if I write to much this first time, excited as I am about having found you.
I come limping in from the audio cold. My 20-year-ago, Albuquerque flea-market-treasure, a Sansui 9090db Receiver, is almost hypothermic. My dusty N.M. years took the first tole. The pots all got The Grit. The volume control got it the worst, so bad in fact that Big Su gradually became all but mute, 5 years ago. At that time, I talked to an audio store owner, one of a very few here in remote, northern N.Y. He said parts couldn't be found for a 9090db any more - couldn't be fixed. That sounded like Dead Mans Curve for Big Su...so...sadly, the once proud Leader Of The Pack was wrapped in black plastic and entombed in a dark concrete cellar. Would she ever see the light of day again?
Strangely, a glimmer of hope came after being sold some new audio components. I assumed my new amp had a preamp...wrong. But I refused to buy the now-necessary preamp for my seldom used but much loved turntable, that, after having purchase a now-necessary equalizer. I have high end hearing loss. And the new Cambridge Audio 540 amp just didn't do it with bass and treble only. What was I thinking, I had lots more EQ (and power to push it) on my old Sansui and I loved that. But now, I admit, I am sold on my new-to-me, used, Hefler 10 band per channel, stereo equalizer.
Still, flexibility was lacking with my new system. Unable to plow my rare platters, I became desperate - desperate enough to entertain the hair-brained idea of exhuming that 9090db behemoth from the willies world down below and running my (slow to start but eventually steady) Pioneer PL51 direct drive turntable thru it. After all, a guy's got to do what a guy's got to do - right? Funny, the sweet satisfaction when that worked.
Some time later, I tried giving Big Su a bit more to do. It just seemed ridiculous to have a 60 lb. phono preamp. That's when I noticed The-Flashing-Red-Light.
One weak channel on a power meter was OK - nauseating - but OK. I'd tell myself not to look at it. (Don't look at it...don't...) No owners manual to figure out how to benefit from the lauded db (Dolby) feature was an unsolved mystery I could live with, I had lived with it for 15 years and figured I'd probably die with it. The increasing crackle of the attenuators, leading to near total dropout of sound, that's what put Su away in the first place. And now this, this unstoppable blinking light - was it telling me...what...that my uncontrollable amp is now dead!?
So what. On the BLINKING bright side, I have the only working 60 lb phono preamp in the world and it comes with a BLINKING RED LIGHT. I've been grateful ever since.
For years though, I feared my big beautiful Sansui was one blink away from total Flat-Line, that is until now, now that I've read all your 9090db posts, all you hifiengine Ame-goes. I now see, you've been thru it. You understand. You haven't given up. Your telling me, Big Su could be, again, the great gal she once was.
I'm not a technician and my budget...it'll be a STRETTTCH...again. But a guy OUGHT to do what a guy OUGHT to do! Write. $WHERE TO BEGIN$.
I'm all warmed up now, thank to you...John
