Thanks for the speedy response Martin. I pulled the back of the defective unit and it is gone. I did find a set of foam repair kits on eBay. Sorted. How much are your cap kits..? Think it is a good time to repair the lot at once. Cheers Guy

Hi Martin, I am also getting a little distortion from one of my redlines. Think the foam must have gone. Can you let me know cost of kits..? I will then send in to a high end speaker repair man to complete the repair. They have not been worked on for some time so think the capacitor set would also be a good plan, so please send me the costs on these
