Just a general statement regarding tubes failure. BUT technically, so I'm not held down by gun point, yes there could be other issues.
Regardless, a visit to the tech would let you know.
Quote: If it is brand new, get it over to a auth Orange tech asap.
Absolutely! Don't stress yourself. ATM it's not your problem!
Quote: I wouldn't assume that just because it had a bad tube right off the bat that there is something wronge with the amp.
I would! A bad tube can cause damage to the amps components.
OP Take the thing back and get it put right. It's what a warranty is for!
