Hello Bigkidz.
I've a SA-5000 for several years. I recently opened the case to clean for dust, with a brush and by blowing air. I've also cleaned the pins of tubes and sockets with an electronic contact spray cleaner. Now i hear a loud whiff or blow on both the channels using phono input (MM). I exchanged the tubes but it doesn't go away. I suspect that it is a problem from power supply, where is the only tube I didn't change. I was attracted from some kind of upgrade, but now i have to repair it, before. Do you have the service manual of the SA-5000? Or can you help me to find it or with any other suggestion? Thanks in advance, Luca
