LMNC Performance filter

Hello
I bought the lmnc performance filter and i got a little problem my R3 resitor burned when i test its the -12v resistor just bellow the power connection.
Here some pictures to illustrate
I dont know if it come from the ribbon cable
Or if its come from the stripboard attached to the pcb ( i check with multimeter no strip is touching an other)
I saw i Forget to solder the power connector to the pcb so i found an other way to power this ( the stripboard thing)
