I have an Invertec V350 that I got in non-working condition for cheap. I did some tests and was able to determine that the switch board has failed. It fails the resistance test and some of the large resistors on it look burned. I have not had any luck finding a replacement board as of yet. Does anyone have access to a schematic that might show what values these resistors should have? They look fairly simple to replace (besides the 10lbs of hot glue on everything).The number on the board is G3830-1 GlenHobart Champion 16Hobart Hefty CC/CVHobart Handler 140Lotos LTP5000D
