Hi All, I'm the proud new owner of an SVT-4 Pro. I found a great deal for a used amp on Craigslist for $500. It's in good working condition, however, the graphic eq is really dusty and the input jack my need replaced (it's a little touchy/scratchy). I would like to pop the top and give it a good cleaning. Does anyone have experience with this, and are there any good rules of thumb to avoid potential shock from any voltages? I'm a bit new to this, but I'd like to get started soon. Thanks for having a look!
