I'm not sure what your saying, but have you tried checking for lose solder joints? Blown caps? Any symptoms or observations would help us to help you.

Hello Ben, thank you for your reply, two of the cap look as if some thing was escaping from them, removed the sold with the rope, and replaced them, thanks again Ben
