Don't worry about the chassis controls, they're fine. The "DC" adjustments on the convergence yoke won't give you any trouble either. It's just those parts contained on thy dynamic convergence board that are problematic because the heat is contained in a small area.

There was one series that had a bagged kit from Zenith to rebuild the convergence board. Came with coils, pots, and a 5 watt resistor IIRC.
