First Post- what not to do


Been lurking for a while and thought it would be instructive to start a post listing "what not to do" as relating to this hobby.
Mine---do not move CD player with discs inside.

Don't buy new tubes for your new tube amplifier before you even listen to it with the ones it came with.  
Don't place your speakers where they look best and presume that's where they will sound best.
Do NOT under any circumstances ever ever get your fingers across the speaker field coil output of an old Wurlitzer vacuum tube jukebox!
