The globar type resistor in series with the power transformer primary provides a controlled warm up and, in conjunction with the varistor, provides the degaussing current. As the globar warms up, its resistance drops so the voltage applied to the varistor and degaussing coil drops slowly. That prevents the degaussing process from ending on a strong peak and disrupting the purity. They were often sold as a set when the TV was popular.
