My Nordmende C-138. This radio is a German manufactured set built for the American market. These radios use a number of Ceramic Resistors, and in my case it is a 1K ohm (at most it looks like 1 watt) which is at fault, having been burnt out by accidental overload. Being that Ceramic Resistors are mainly used for their ability to dissipate heat, my question is whether I should swap the new resistor out for a like resistor (should I be able to find one) or should I use another using a different insulator type???? Any thoughts on this would be appreciated. My thought is that, should I use a standard resistor type the worse that could happen would be that it too could overheat and burn out, without burning the house down, being that it is not a high wattage resistor.
I wouldn’t worry about it too much. To be on the safe side you could use a 2W flameproof metal film type – widely available.
