The other day a friend brought over a Gibson amp for me to look at. The speaker is obviously blown because it makes this rattling noise. I removed the speakers and when I pushing it in, it made that scraping noise. The amp draws 30 watts from the wall and it is not very loud, but it sounds like no other small amp I've heard. I know I can handle rewiring it and replacing the pots and all that, but the speaker needs a good recone. Is there a site that will sell me the parts needed, not in kit from or "service" form. Thanks
