Bought this off eBay for $12 + shipping. Was dirty, one channel was out. Cleaned inside and out and replaced fuses. I am blown away by the sound of this 40 year-old amp. The 40 WPC is PLENTY for my large-ish great room - cannot turn past 12:00 without volume becoming ear-splitting through Athena Technologies AS-B1-1 bookshelf speakers. Even through my iPad music is detailed, expansive, full, with great low end. I know Rotel is considered “mid-fi,” but this is plenty of receiver for me.

A lovely receiver to look at as the music plays.
great quality and very well made, strong and a bit heavy.
Sounds great and loud with 2 12inch speakers 8ohms each and dome tweeters, speaker boxes H/W/D/ 30 inches / 15 inches / 8.5 inches, and each speaker has a 2 inch air hole in the front, the reason im giving detailed info on the speaker is because i went though hell trying to get the best for this amp, i started of with 8 inch 4ohm speakers but the amp did not like them, with the speakers ive got now this amp is pushing out more then 91db @ 1 meter i know the bass is going though the ceiling, and still a heavy warm bass with the volume low, the speakers im using are ones i built, this amp will sound just as good with port speakers / bass reflex, floor standing 91db@1 meter. This is fantastic receiver.
