bpolettiGrab a small allen wrench (usually plenty around audio equipment) and MUTE THE SYSTEM. Touch the allen wrench to the preamp chassis to discharge any static"
This is such silly advise there is nothing magic about an Allan wrench there is no reason to use an Allan wrench at all in this circumstance unless you need an Allan wrench to mute your system which is just about impossible a requirement you can just touch the chassis with your hand its probably a better conducter than the wrench!
