A useful tip when you disconnect the cathode lug of the socket run a wire from it to the top side of the chassis and add a fuse holder above chassis. Ground one side of the fuse holder, and connect your cathode wire to the other. When you're using the TV as a TV install a 250mA fuse to protect the flyback...If you ever need to check the cathode current all you have to do is pull the fuse and clip your meter to the terminals of the empty fuse holder.

Adding that fuse/holder above chassis both gives your flyback added protection and and gives you a convienent cathode current test point.
