Did notice some distortion at high volume level (Jack Johnson). The first time though the wife didn't turn off the loudness button. But the second time it happened to me I also had to adjust the equilizer I think I had to tone down the base. Jacks recorded pretty loud I think. Do you know of any other reason for this.
It is an old Jvc RS 77 reciever from 82 but it's still going.
