    Hi Jay, It looks to me like the heat has also carbonized your board somewhat. This weakens the board and may cause the pads to come loose when you try to remove the old parts. In circumstances similar…

    This <<<<<<<looks to me to be what i would use to replace them with,:

    image

    I may be wrong with the conversion, but they should be correct.

    How i would do it is, solder the new resister onto the old axel leads, than after everything is soldered,

    snip the old resistor off. that way you wont bother the traces hopefully.

    I have learned this from experience, the hard way.

    Using the old resistor as a sort of heat sink until you are done.

    I hope this helped.

    I ordered 250, dose the size deference seem right?  How do I know what watt the old resistors are rated?The old ones read 2.20K and the new ones read 2.18K, I guess that is good but I'm worried about the watt rating.imageimage

    if your concerned with the smaller resistors then connect 2 in series with 2 in parallel, this will end up with the same value within the tolerance of the resistors but it will handle much more power

     

    this would require 4 resistors for every one your replacing

     

    alternatively get higher wattage resistors

     

    Regards

    @peter oakes

    If you had to guess, what wattage would you say the old resistors are?

    1/2 watt?
