With static electricity in this cold dry winter. I fried the right channel of my Classe Amp last night with the touch of a finger. I usually have anti-static sheets in hand before touching anything but this time did not.
One blessing of living in Florida I guess, no such thing as a dry winter....or any winter really come to think of it...... Sorry to hear of your bad luck though.
I've been digging around inside of electronics for 25 years and of all the modes of failure I've come across I can't say static has ever been one. I've delivered some bone-jarring static charges to my gear and never so much as a tick from the speakers. I'd suggest having the grounding scheme examined. The circuits shouldn't be the path of least resistance between the chassis and the ground.
Static can and does impart damage. Mosfet transistors and ICs are particularly susceptible. Some people destroy electronics with static unknowingly. It doesn't always happen with an obvious shock.
