If this was without the 6080 plugged into the socket, perhaps redo these measurements with that tube in.

With the 6080 plugged in, the only ones that changed was B3 stared at 14Kohm and rose from there and B6 was 26Kohms and rising

There isn't really anything here indicating much of an issue.  You could try a different 6080 just to rule that out.

It measures the same with a 6AS7G

Can you post a few more build photos at some different angles?  There's got to be something at work here that I just can't see.

Clarification here might help. Amp blows the fuse when turned on with 6080 in, yes? I see that you measured the resistances with a 6AS7 installed. Did you also power it up to see if the fuse blew with the 6AS7 in the socket? If the fuse holds and voltages are OK with the 6AS7 it could be the 6080 was damaged by the initial miswire.
