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?

No. There are many Sugden class A amps and integrateds going strong 20 to 30 years later....take the A21 for instance.
mrmeaner13 posts06-13-2021 2:47amI have a glorious Class A Sugden A21SE and it never misses a beat, I contacted Sugden and asked them about having it serviced and he said it’s likely not to need looking at.
In my opinion class A can’t be bettered.

It is a fantastic amp! Mine is driving Tannoy Eatons with no issues. There are original a21’s still going strong 30 years later....Sugden, the very first commercially available solid state pure class A, since 1967. Some very ill informed people post here....notice the gigantic heat sinks that adorn both sides of the A21se...the amp is a brute! It is liquid, textured, detailed, holographic, and powerful...at only 30 watts/40 into 4 ohms....50% larger power supply than the previous A21 model, non se version. Built in the UK by one of only 12 employees...even comes with a tag indicating all who had their hands on it...worth every penny of the $3250 paid. When combined with Tannoy legacy, prestige, or gold series speakers, it is pure sonic bliss...end game combo. Add your own tubed phono preamp and it gets even better...Tavish Design makes some great phono preamps.
