Pull the tube. Turn on the power. Does it still blow a fuse?

My HB 6M amp now blows the fuse in the HV line. I opened it up and after 
disconecting the  anode from the circuit, I get abt 12 megohms from the anode 
to ground. I've never measured one before but assume that is not right and I have a 
shorted tube. If that's the consensus here I'll open up my HB HF amp and pull that 
tube to test 6M.Thanks, Dick NY1E
P.S. I can't complain, I bought the tube for $250 22 years ago....
