If you are thinking about old Fender amp designs go here http://www.allenamps.com/ I been thinking of buying one of his amps for years.
DreamTheaterRules — Aug 13, 2008a common problem to combo amps is the tubes being subject to vibration. The audiophile speaker makers have been after every sort of damping substance and method for years to kill vibration in speakers/cabs. I've always wondered why combo makers don't put some sort of vibration damping material in between all the places where the amp section is mounted to the cab. It really would be very easy to do.
