Fuse blown at first Powerline Voltage Test [resolved]

Can you post the voltages for terminals 1-10? Can you also post some photos of the build?
141V at terminal 9 means that half the 6080 isn't conducting, which could happen for a variety of reasons.

So sorry fellas but after reflowing it seems one wire no longer had a firm hold to the octal socket, made a final reflow (then obviously retook measurements which were *all* within tolerance) and now everything is working, crack is pumping jams.
Thanks for the help and for sticking with me while I did the build. I will be doing the speedball also at some point but for now I just want to get used to the sound of the stock crack, give the tubes a bit of time to come into their own etc.

Back again. Amp was working fine for about 8 hours, turned it off a while and went to do other stuff for maybe half an hour. Came back and switched the amp on, as the filaments began to glow up the 6080 tube visibly sparked and there was a loud pop in my headphones. I've attached a picture, in it you can see the two metal rods inside; one rod appears to be burned and this is where I saw the spark. I turned it off immediately and haven't turned it on since; wondering what to do now?

Turn it on and check your voltages.
It could be, or it could be a little residual gas in the tube that needs to cook off.
