Class A amplifiers

I was watching YouTube reviews on Hifi and one guy said if you like Class A amps you have to accept that every 3 or 4 years you have to send them in to get serviced Becasue the heat inevitably causes issues? Is this true? I have a friend with an older Maek Levinson Class A amp and he was looking to sell,it to me, and am just wondering if Class A amps are like a boat, always costing you more . Anyone?

I think this should vary greatly based on thermal design and usage. No reason why a Class A amp of any rating can't be designed with enough ventilation and heat sinks to last a lot longer than that.

Is Your particular Class A amp going to last 10 years before servicing? I have no idea. :)
