Hi guys, just noticed this crack in my laser tube!
is this game over for my laser or can it be repaired?

Did you run it without water and then turn the water on? That can crack the tube. I would see how it goes as the crack looks like it is in the water jacket only.

No, I think it could have been damaged in transit. I’ve since put thermal silicone around it and I am being sent a replacement tube from China free of charge. Result!
