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?

I've heard a few Rogers amps here and there and they seem to sound great...I know somebody who owns one (EHF200) and loves it. A Lifetime transferrable warranty on everything they sell (beat that!), hand built with point to point wiring, great reviews (except for claims that the 65V-1 has bass issues or something)...what's not to like? Sort of pricey, but possibly worth it.
Received new MC275 yesterday. Units On/Off switch doesn't work. Amp only shuts off when you unplug it.  And no, I don't have any triggers attached to it.  Most disconcerting considering I waited three weeks for it.  I've read Mcintosh has lowered the bar the last couple of years, but this is aggravating.  Would not recommend this amp!
sorry to hear. McIntosh is one of those great "classic" American companies. Let's hope McIntosh does not go down the path of older "classic US names" like GM and start building junk.
