Re: Toshiba 42H82 Fusible Resistor Wattage Revision


It is not possible to do more than guess from a visual insection. Regardless, I would use 2 watt resistors. The power rating is simply the maximum that they can dissipate before burning up and has no effect on the performance. As long as the resistance is correct and the power rating is at least what is needed, larger is not a problem. These are not designed to fuse to protect the output ICs. On the contrary, over rating them in power is safer, because an open resistor is more likely to cause output or damage to the yoke or even a CRT. In circuits where the resistors are designed to act like fuses for protection if too much current flows, you would not want to over rate for power. This is not one of those cases. i.e. when in doub use the larger power rating on convergence OUTPUTS. Just make sure that they are flameproof, metal film, or wirewound resistors and not carbon resistors.
