To me,the spc50 was like a leap backwards,being a positive pressure stove.Have seen lots of complaints.Anyway,you might want to consider buying hi-temp self adhesive insulation,and install inside the stove,around the auger,hopper,etc.You can find it at hot rod places,Jegs,Speedway,etc.Sometimes just taking out the vibration of the sheet metal can make a big difference.
