tube question

["Daniel Hein" <slimz57@xxxxxxxxxxx>]

Hey folks,
My guitar player mentioned something about changing my tubes every coupla 
years.  I've had my amp for maybe 5 years, with the same tubes.  To my ears 
it still sounds good, but maybe if I change the tubes it'd sound better?  
Does it depend on what tubes they are (who manfuactured them)?  I don't know 
who made the tubes, the amp is a Sonny Jr. 2 and it's the stock set-up if 
that helps.  Don't know if the pre-amps wear out faster than the power tubes 
or what.  Any help would be appreciated.

Thanks,
Dan
