The tube isn't dead, it's still lasing a bit, don't do anything destructive! Not having a solid plasma channel in the bore is why the output is low. We don't know that there is anything structurally wrong with the tube at this point. Photos look OK unless I missed something.
The problem is that the water cooling is functioning as a low resistance path for the HV current. Increase that resistance (dramatically) and you will save the mirrors (and the tube as a whole). Personally I'd flush the tube with alcohol, blow it dry, and then use mineral oil (cheap grocery store stuff) for cooling. Run it that way and see how it performs. It should be like it was when dry, but without any of the overheating risks. From that point on, we can see true tube health, and delve into power supply concerns.
