Since you're ordering parts anyway, just get a new Molex plug and some terminals and make up a little dedicated resistor load bank you can just plug in to the power supply. The plug is Molex p/n 50-84-1090 and the socket terminals are p/n 350536-3.

Scott,
The damaged resistor is on the +15 volt line, but the foot switch issue you mention makes me think of another (ghost) short I had some while ago, which happened only when the Yamaha foot controller was connected on the back.Since then, It stayed unplugged the time to deal with that, but never really analysed the cause behind it in the end...Well, one thing at a time, for now it's the PSU first ;-)
