I am a newbe and don't know all the lingo but do need some help. I have a Technics SA-G9057 that has intermittent static on the left channel. It doesn't matter what the volume is set at it is always the same db of static but the funny thing is that it will come and go. I have checked all connections and changed the speakers but it made no difference. I think it actually kicks in the cooling fan sometimes. Any help and/or suggestions would be greatly appreciated. Thanks in advance.
