Musical Fidelity strange noise. HELP


My relatively new Musical Fidelity KW550 integrated amp recently started to have static-like noise only on left channel. The strange part is that it doesn't change by volume control or mute. It's exactly the same volume regardless the input or level of the volume control. It seems like once the unit starts to warm up. The noise gradually decreases and disappears.
Anybody can help me with this please? Thanks in advance

I think I had something similar with my M3 I bought used last fall. I could hear a sound like static on the left channel. The bad news is I never figured out what it was; the good news is it went away. Haven't heard it in several months. May yours do the same.
