Yes, indeed, while you are ordering parts, measure all the resistors including the candohm. If any are more than 20% out from the stated value, or if the resistor is marked with silver, 10%, or gold, 5%, and beyond that tolerance, replace them. I never order smaller than 1 watt resistors these days, and I buy 1% metal film types. They are much smaller than the old carbon composite type they replace, and are smaller for higher wattage, so can handle over current better should that occur. I often use modern 3 watt metal film type to replace the old 1/2 watt because they are about the same size ! If the candohm is bad, or any section of it, feel free to ask folks on here about what wattage resistors to use in replacing it, or a section of it.
