I just received a Sovtek 5Y3 destined for my Clarinet. The whole glass and internals are tilted off to one side, like the Leaning Tower of Pizza. I have no way of testing it, short of plugging it in, and I don't want the thing blowing up on startup or something. Is this cause to worry? Should I send it back or give it a try? I am just starting the build, so nowhere near ready for it.
