If one were stupid enough to want to attempt this again (76V), with different FETs and main caps, what FET would be a good candidate?
Sounds like toast.
The stickies on Clyte controller repair have loads of info on FETs, caps and the other goodies that make controllers work.
For a 72V brushie, I'd look into the deal ES members get on ecrazyman controllers, rather than fixing the blown unit.
