That "resistor" sounds like a ferrite bead.Probably looks burnt because the glue they use to keep it from vibrating gets hard and turns brown.The only resistors in series with the horizontal output transistor are a wirewound 10 w in the bottom rear of the chassis (usually 10 ohms) and a 1.5 ohm in the emitter circuit with a 47Uf capacitor across it in the emitter circuit of the transistor on the rear of the chassis near the horizontal drive module.Both were high failures.The 1.5 ohm fails because the 47Uf capacitor dries up.There will be no high voltage if the wirewound opens so the transistor won't run hot but the other resistor and cap don't open totally so you can get reduced drive and width and the transistor can run hot.Most likely if the output transistor is getting hot the tripler has failed.They fail rather suddenly.Be careful of powering it up in this condition as the shorted tripler can take the flyback with it.The easist way to test is to unsolder the high voltage lead from the flyback to the tripler and move it as far away from the terminal and any other terminals or metal as possible.Then fire the set up.You will hear and possibly see corona from the flyback lead but the transistor will run cool if the tripler was shorted.If it still gets hot need to check for other problems.If the flyback is also warm or hot then it's bad.Replacement triplers can be still be obtained for these sets.
