It'll probably out live their grandkids too<:-)) The only complaints I 
have for legal limit amps is the thing is so darn big and it takes 
forever and another day to warm up.  OTOH I automatically turn my amp on 
every time I turn on the rig.

Of course the 4CX3000A7 is big too and you have to hunt to find good 
sockets for a half way reasonable price.  Most on e-bay come without the 
two mounting/cooling rings.  OTOH it's almost instant on, but takes a 
bit more power to light the fire.
