Heh, heh. I'm not that easy to piss off...
Still, something looks awfully hinky when you look at the bottom of that amp - the panel on the bottom part of the amp is very dark and stained and is even loosening from the wood, but the covering wrapped around the bottom of the side panels adjacent is very light and clean (it also looks like the texture on these panels is finer, but that could just be a trick of the lighting and camera).
Still, hard to imagine how the bottom edge of those end panels stayed so pristine when the bottom panel immediately adjacent is so damaged...
Also, BTW, you haven't mentioned how the amp performs. If you've just aquired it you might want to pick up a can of Deoxit as I wouldn't be surprised if the electronics don't have a few corrosion issues unless a good tech has already been through it. I've been in electronics for years, including designing and building tube amps, and it's hard to imagine there not being some corrosion issues in the sockets and such with that much water damage on the covering. I know, the chassis is a foot above the bottom of the amp - but you don't generally get that much damage from moisture on the bottom and not have some pretty significant humidity around the chassis.
Of course, if it's been serviced by a tech then probably the first thing he did was break out the Deoxit... My brother rebuilds "boat-anchor" ham radios and buys the stuff by the case.
