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?

My Altec Lansing 1570B were built around 1954 and run fine.  They were rebuilt in 2004 but the transformers, chokes etc are all original.  
Anyone with experience to share regarding Rogers EH series? I found a dealer within a one-hour drive and like the looks...and obviously the specs looks great.

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.
