US made, integrated tube preamp able to handle KT150 tubes?


I know that foreign made can still be excellent equipment, but I like the idea of support being "local". No offense...

Suggestions? Preferably less than $5000

Aric Audio’s Transcend Push Pull has exceptional sound quality and is a tube rollers dream. It uses EL34, KT88, KT120 or KT150.
Primaluna is top of my list, but any issues with where to go for warranty work (made in china)? I know any reputable local dealer would offer some level of support (?)
