I'd probably get 6J5 (metal version) replacement, they are plentyfull and inexpensive. If the readings are so very low, it would be doubtful if they were any good.
Pin 1 of the metal variation is the connected to the metal shield, obviating the need for a separate tube shield. Just check to make sure pin on on the socket is not used as a tag of convience, and do ground it. The 6C5 can sometimes be used as well, so if you have some, no harm in trying.
