I searched for an old thread about an SWR SM-900 that had taken a tumble. I think it was posted by someone named Amy, username was clatteramy or somesuch - anyway, she must be gone because I can't find the post, showing pix of an SM-900 that hit the ground while housed in a rack case. The front panel was warped because all of the weight/force was borne by the rack mounts on the front panel. Let me tell ya, my SM-900, in a rack case, fell about 6 feet down and hit concrete, and the warpage is much worse than the pics Amy posted. The rack handle on the right hand side now points inwards! It's times like this that I wish I had a digital camera, so I could post some pix. I rushed into the club and set my rig up to see if it still worked and I was greatly relieved that everything seems to be working fine. Whew! New rule - the amp gets carried separately from now on -- no stacking on top of castered cabinets!
