in Power Genius XL Amplifier

Hi All,

Discovered today that while in Stand by mode the amp is doing a strange noise when i touch a bit my desk or when there are slight vibration, the noise looks like a CPU heavily working, just when I have the amp having vibration, when in Idle/Operate this is completely gone.

Any idea what it could be ?

    Could it be dust build up on the fan blades? I wish there was a removable air filter on both the PGXL and the 8600! There are too many screws to remove.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
