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?

The only cost a good Class-A amp does is raise your power bill and room temp if left on for no reason, a large biased class-A actually runs cooler when played hard.
A Class-A amp is the best BUT!!! it has to handle everything that that high Class-A bias is sucking out of it and it’s power supply, if all is designed correct nothing but nothing touches it. (in the distant past, I made huge "water cooled" two man lift ones that were 150w based on 20w 1970’s Nelson Pass bi-polar class-A, that today still have never been bettered)
