Sony STR-DH100 2-Channel 100 Watt Stereo/FM-AM Receiver with Remote - Tested (Input Select, AM/FM, bass, treble, master volume, muting, power, speaker A and B connections) and fully functional. Included remote is a Sony model RM-AAUO22. User manual indicates original remote is RM-AAUO55. The 2 look very similar, but there are a few differences (don't see bass/treble +- on the included remote for example, plus it has some additional controls not available on unit) but basic remote operations work ( power, volume, tuning, muting, etc) with included remote.  

Unit is in cosmetically excellent, like-new condition (see pics)
