You could try a radio shop that is willing to give a go at it, you could try an electronics outlet that specializes in small repair, while that unit is made by GRE , you could send to USA for factory repair, you could try local career college that has electronics dept and see if dept head is willing to give it a go. Problem is they will look at it and say I dont have part , depending on condition of BNC connector, as it has a pin that requires to be re-soldered to pcb board, you also dont know extent of damage to PCB board where it mates to chassis. Your best bet enquire with GRE USA and see what they say. You could look to see if there are other guys in Regina that still do electronic repair. (Yellow pages)
