Integra A-817EX Integrated Stereo Amplifier (Defective) Model: Integra A-817EX - Brand: Onkyo - Type: Integrated Stereo Amplifier In the SOURCE DIRECT position, sound comes out normally from both left and right channels. However, in the TONE position, the left channel (Lch) has no sound. If listened to in DIRECT mode, both the Lch and Rch sound like the unit should, and can be played with CD and PHONO. I will sell this to someone who can repair it or who can make effective use of it for parts. Thank you for your consideration. Thank you for viewing.
