u7100 had burnt pin (20). I replaced it. Both sides of L7101 and L7100 start at 72 Ohms and drop very slowly. I held it for 3 or 4 mins to about 60Ohms then took probes off. I think it would have continued to drop. So maybe a small short? I dont have a donor for this... Do you know of any other boards with compatible FETS?
