[QUOTE="kubusi, post: 750243, member: 19010"] Here is a little trick which sometimes enables you to determine the value of a burnt out resistor, you need a fairly accurate ohmmeter. The chances are that the resistor has gone open circuit in just one particular spot. Put one probe as close to the middle on the burnt out resistor as possible and then check each end to see if there is any continuity,if so measure the resistance and the original resistance will be double the measured value. There is a chance the overheating may have changed the value of the conducting section slightly, it will still be close. Give it a try. [/QUOTE]
