I was cleaning my gear over the weekend, specifically my UPA 500, to remove the dust that inevitably settles on top and around it. I decided to use one of those swiffer cleaning pads first as I wanted to pick up as much dust as possible to prevent it from moving into the top grill holes of the amp and got quite a nice static shock while doing it. Could it have damaged, or does static on the chassis the potential to damage, the amp or the other units connected to it? Is the chassis grounded seperatly from the internal components etc? Can it travel through the unit up the component wires etc? Im not much of an expert on static and electronics except for knowing it isnt good. Everything sounds good still but would like to put my mind at ease.
My anti stat spray and a microfiber cloth is all I will use in the future.

Usually the case is grounded through the third prong in the power connector. If your power connector has only two prongs, or if your using a "ground buster", then it is possible to damage the internal components with a external static discharge.
To lower the instance of electro - static discharge, set up a humidifier around the equipment your working on.

Was your amp turned off? I would use a can of compressed air personally.

The UPA 500 and all the other units connected to it (UMC 200, USP 1) were in standby mode with the yellow power lights on. Everything is three pronged and grounded through powerbars.
Ive listened to some music at decent volume levels and everything sounds great.....though I thought I heard the occasional static click or higher frequency noise. Whether this is my ears "looking" for issues or not Im not sure.
Would a static shock causing damage just kill the amp outright or could it introduce noise into the channels and the speakers etc?
