and matt if your dmd driver pcb isn't badly heat damaged just rebuild it (HV section). I do these on a regular basis. I replace every component good or bad including bridge rectifiers. (I always do a full rebuild not a partial patch up)

but if the board is heat damaged then the homepin board is the way to go

No heat damage luckily, are the components available locally Andrew? I know Great Plains used to sell a kit but I haven't got around to sussing the rebuild out yet
