Harman Kardon AVR 230/230 Home Theatre AV Receiver. NO REMOTE. Unit turns on and appears to run, unable to test input or output due to lack of knowledge and space to set up with speakers. Previously believed to have been used with a Bose Acoustimass 15 II Home Entertainment System. Unit is in good shape, might be a little dusty but no damage to be seen on outside. No other connection cables with it.
