Yamaha Rx-1100u

I bought this unit on a whim from a guy in Hawaii. The unit was supposed to be the best of Yamaha's consumer stuff combined in 1988 >>> a T85 tuner, a cx-50 preamp and a mx-50 amp. just wondered if anybody has any info on the unit as the internet isn't giving up much answers. makes 125rms at 8ohms and 190rms at 4 ohms. I have to wait three weeks to allow the "pony express" to deliver it? any comments welcome
