0.8 ohms doesn't sound that unreasonable for the cold resistance measurement of a UU6, some of that resistance will probably be made up by the resistance of the meter leads, I would check the valve holder sockets for tightness to the valve pins and the valve pins and holder sockets for muck (oxidization)
