Hello. I came on this website while trying to troubleshoot some equipment that I have. I have a couple of vintage pieces that I am having trouble with. Hoping someone here can either help me with what I have or would maybe have use for it. I hate how we live in a "throw away" world and am always finding old stuff to fix. Anyway, I came upon a Kenwood KT-7500 at a garage sale. It has been sitting in the attic for a few years next to a Kenwood KA-6500 amp that I found the same way. Anyway, the KT powers up and has sound, but doesn't turn up very loud and I mean it is really low. I cleaned it with the stuff from radio shack that someone suggested and still the same problem. The KA powers up but that's about it. It has five fuses inside and one blew right away when I replaced it. Anyway, Like I said, just hoping someone here can help me out as I do not know much about it. Thanks HB.....
