What's the funniest or dumbest thing you did?

The absolute dumbest thing was setting the speakers on the window sill of a 2 story apartment so it could be heard outside. Fourth of July party, playing some patriotic music loud when crash, no not a cymbal but one of the speakers falling 16' to the sidewalk below.

Ive never done anything stupid (knock on wood), but my friends dad who got me into hifi punched a hole in the surround of the woofer in his speaker while commenting that it was amazing that hes never had to refoam them yet.

I was in a hurry to put a new NYAL Moscode 300 Maxi into my system. All of this shuffling combined with living in hot Arizona worked up a sweat pretty quickly. As I was plugging in and turning on the Moscode a single drop of sweat rolled off my forehead and fell through the vent slots onto the board and POP, CRACKLE, SNAP. I dove to shut it off and it was too late! I took out one side of the amp!

Jothompson.....I had a similar experience years ago with a Mcintosh 225......I stepped out of the shower and stupidly walked into my bedroom to adjust the volume on the preamp before fully drying off a single drop of water off my hair fell onto the amp and poof!!! luckily it only fried a tube,unfortunatly it was original Mcintosh labled

I had unknowingly stumbled upon PERFECT synergy in my system... I enjoyed it at every opportunity, transfixed... friends would congratulate me, people would ask how I managed to get such amazing sound from such a simple looking system, even my wife began requesting music.... then I realized that I could probably get even better sound.... 2 sets of interconnects, and a tube swap later, the magic was gone............. I've been 'upgrading' ever since!!!
