Though I see you found your answer, for the record I'd remove the tubes and ship them separately. Lighter packages have a higher chance of survival because they bounce. Read the shipping horror stories on here. Heavy packages get smashed.
Shipping tube amps, leave tubes in or out?
Hello, I'll be shipping out a pair CJ Premier 5's tommorow which have a fair amount of tubes in them (under a cage) and am wondering how most people ship their amps...so far I've had success leaving them in as it makes more sense to me, the tubes can't move around and are protected by the cage, thanks.
