Hm. Possibly a bad tube. If the RF section of the tube is conducting, there should only be a very small fraction of a volt on pin 8, readable only on the lowest V scale on the meter. That's because the low resistance of the coil, only 10 ohms, will drop very little voltage at the current the tube pulls.
When you go to have the tube tested, be sure the tester will do both sections of the tube independantly (not a "drug store" type tester).
