Slight hum from SLI-80 power amp


I own an SLI-80 Amp for a little over a year.  My system has developed a very low, slight hum only on the right channel. One has to get right up to the speaker to hear this hum, but it is still a hum that should not be there.
Any ideas where I should start looking to eliminate this hum?  Thanks

Cheater plugs should only be used as a diagnostic tool, they are not meant to be a remedy. Please remember that Cary has a 3-year warranty if you need a tech to look at it.
