Ghost Issue

[walterbeers]

I know delay lines seldom fail, but just for curiosity's sake try putting a clip lead across the 2 ends of the delay line. Don't clip anything to the ground side. and see if the ringing (or ghosting) disappears. I battled this exact problem for months before I found it. The "new" delay line solved the problem. I guess I'm really curious myself if that's your problem or not.
