Compact size integrated DC amplifier. I was able to play CDs by connecting a CD deck to the aux input. The phono lamp doesn't light up, but I can listen to records by connecting a turntable (record player). Operation has been confirmed with a brief, simple test, so full operation is not guaranteed. Not all functions have been checked (other tape-related functions, etc., have not been checked). Sold as junk. Everything in the photos is included. There is some dirt.
