Hi all, I've just recapped my Quad 306 and it still works, which amazes me! I may get the bug and start recapping other stuff, but I suspect they won't be as easy as the 306. However I need to reattach the pad that was attached to the inside of the top cover as it has fallen off. I'm not sure what the material is made of and the amplifier gets hot. What sort of glue should I be using?
