Hey man, I never had a problem pumping 70V 15A through that thing. So dont blame me on making the traces too small! Something just had a hard short and blew a trace instead of a mosfet.
Least you had a fix. I would have used a copper wire..lower resistance than all that solder. But hey, Least its a fix!

Ya, my IRFP150s may have blown when I hit 50V to it, although they handled it many times before no problem. And When I was drawing 5 inch 3/4cm thick arcs, I noticed the PCB was very hot, and this time it was not the 470 ohm resistors getting hot, I believe it were the traces having a hard time. Well, I know what power to keep this board at now anyway.
I didnt use all solder for that, I have copper wires under it with a lot of solder holding it together.
