I’ve had my eye on a mark v for over a year. Locally there is a Bubinga combo for $2k manufactured in 2010 in mint condition (TBC). Is there any risk of a 13 year old Mark V lasting another 30 years? I have no intention of selling this amp. I am even considering a new combo for $3k since it will be 12 years newer with lower age risk. Looking for some advice based on experience.
