It really depends on how much the equipment is used as to how long the 
electrolytic capacitors last.  The more that the equipment is used the 
capacitors last longer.  Sitting in an unused state for long lengths of time 
results in premature electrolytic capacitor death.

Pete,

My understanding from input received on this reflector is that the electrolytic 
filter caps have reached the end of their lifespan and
are prone to go out after about 15 years.  This varies of course but it is good 
idea to change them out if they are as old as yours.
The problem with these guys is that when they go you don't normally have any 
pre indication and they usually go kaboom and take out
other stuff along with it.  Cheap insurance to replace them.
