PL puts on a good show but bottom line: made in China. From the way you describe it, "some of the tubes were a little crooked" sounds like they ship with tubes installed. You're new so won't know this is a bad idea. If you ever have to ship this please do the right thing and pack each tube individually in its own padded box.
At this point I would be looking to exercise the no-questions return policy that I would have secured as a purchase prerequisite. For this very reason. If they can ship new tubes and you are willing to wait for that, fine. If the amp has to be shipped back, even better, as this is the ideal way of getting out of this deal. Then with your refund you can buy a Raven Nighthawk that is made in the USA and with better tubes and better sound and be supporting some serious audiophiles right here in America and not you know who over there instead.
