I wonder if anyone can help i have a beomaster5000 tuner/amp that keeps turning its off. It stays on for about 10 sec, it will do this about 8 times then it will stay on for hours no problem, but it does sometimes become hot when in use. It is the same every time and its not random. once it on its on!! I find it strange most electrical items will either work or not work . Maybe it just needs a service i have owned it about three years and was supposedly reconditioned then. any help would be appriciated. thanks.
