Be Careful!

Another solution is to have something metal that is not part of your audio system on your audio rack, maybe the rack itself if it's metal,  and rap it with your knuckle before touching your gear.  Your knuckle is much less sensitive than your fingertip and the rap spares you that unpleasant little shock to the fingertip.

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.

@wolf_garcia will fish work?

@uberwaltz thanks!  Fortunately I have back up amps so I am back in business!

@tomcy6 I normally do just that but for some reason I got lazy. And paid!

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.
