25 years old Air Tight ATM3. A timer had to be replaced 6 years ago and a couple of resistors. That’s it. 12 years old Air Tight ATE2 preamp. Nothing needs to be fixed yet.
Highest BUILD quality tube amps?
Not so much with sound...lots of ways to fine tune thru tube rolling, etc. I'm just curious which tube amps are built to last for many years with the least amount of repairs. I know Mcintosh comes to mind for longevity. I was snooping around on the web and Air Tight seems to be built like a tank and I've never read any poor repair histories. Luxman same thing. Any others come to mind?
