What is a 508X tube?
Loctal sockets are notorious for developing bad contacts. One way to clean them is to squirt the tube socket holes full of contact cleaner, then quickly plug the tube into the socket, plugging and unplugging it a few times. A better way is to use a tiny file, available from welding supply companies. Don't over-do it with the file, clean gently - just enough to knock out the crud without damaging the socket.
