Quoted from Patofnaud:
As for the resistors, read Vid bulletproofing guide, remove those resistors all together along with the 'TIP' transistors and install SCR's and jumpers and never worry again.
As for the wire soldered on the driver board, thats a standard 'oops my connector burnt so I'll do a bypass' hack to keep the board running. Simply replace the IDC connectors/pins and you'll be all set.
Again Vid's guide details all of that.
I agree, I did this mod. Those resistors just bake. There is no heat at all with the mod. It must also reduce strain on the transformer.
