Nope. The 1004 filament is connected to the two base connections, with no connection to the shell. That is the key. Whatever you have in there is (incorrectly) grounding through the shell

I figured it is because of the missing fiber gasket that holds the wires and spring from touching the shell and grounding it. See my pic a few posts up, there is no insulator in the socket. One of these but with 2 wire holes...
