Here you go,Rotel collectors. This is a very rare piece that works, but has an issue. It’s very clean on the inside. All inputs were tested and they work,all knobs move nicely. The problem is the left channel is playing louder than the right channel which clearly shows on the VU meters. when you turn the microphone knob to the on position and move it to the center it sounds equal. I tried a little deoxit but had no luck in solving it. my guess is this unit needs a thorough cleaning by someone who knows more than I do. please inspect all my photos and ask all questions before placing a bid. Also understand that this is a PARTS OR REPAIR UNIT AND THERE IS NO RETURN ! If you don’t agree with this, DO NOT BID ! look at my feedback for packaging and rest assured it will be done right for safe arrival. Don’t let this get away, I haven’t seen one on eBay for the longest time. It’s rated at 45 watts per channel @8 ohms but if you are familiar with these units you know they are underrated. made in Japan. Don’t let this one get away. I might be sorry I did.

Item functions. All knobs and switches work as expected. The problem is that there is a nasty ground hum that comes and goes on all functions. I have tried both phono ports, both AUX ports and the tape monitor ports and there is a pulsing hum that comes and goes. I took a quick look inside to see if there was anything obvious about the ground cables or anything that was weakly soldered and nothing stood out. This is sold AS-IS with no returns. You are buying this well below market and if you can find the hum issue you will have a great integrated amp well below market value.
