Dropping resistor repair

.
My dropping resistor blew so I looked up my resistor options on my favorite electronics websites, Digikey and Mouser.

I couldn't find a ceramic resistor option I liked so I bought a thick film resistor that could be heat-sunk. It can operate at up to 100W if properly heat-sunk at room temperature. I probably didn't need to but I added a TO220 heat sink to the stock housing. I used thermally conductive RTV between the resistor and original housing, as well as around the solder joints. I used Arctic Silver between the heat sink and housing. They are all held together tightly with a 6-32 screw.

Re: Dropping resistor repair

How is this holding up? I am very interested in doing this myself.

Thanks!
