There is plenty of help here. Everyone is just thinking about which answer to give. I have had a question in another forum for weeks. So I am convinced it must be a pretty good one if everyone is still thinking about it.<br>Sorry I don't have an answer for you, I do not work on electronics just hard wired circuits, switchgear and motor control. But, I didn't want you to think you everyone was too rude to answer. Good luck with your stereo
