On the way to work, right around the corner from home and just a few minutes ahead of the trash truck, I drive by a box sitting next a large pile of garbage that clearly says 'Sansui' on it.....and I screech to a halt. A quick peak inside, and it really is an AU-666 integrated amp, in the box with original packaging! In the trunk it goes. It was sitting on top of another box - a quick peak and it's a Yamaha CT-410 tuner, in it's original box too! Cool! 5 minute later it starts to pour rain. So, they were saved from getting soaked and then brutally crushed - I feel pretty good! I even have a CA-400 amp to go with the tuner. (Might get pic's up later tonight.) So this makes 8 integrated amps floating around the house...and the 4th one under 40 wpc. (I'm betting they work fine and just need cleaning.)
No scratchy controls at all - DC offset below 50mV on each channel so I hooked up speakers and listened a bit. So far I'd say the amp is really nice, possibly the best of the sub-40wpc amps I have. Pretty heavy too.
