CJ has kindly updated the information at the beginning of this thread so we can now see the differences between the 10468 mic transformer and the 31267 wired backwards. It is clear that the 31267 line input transformer has about 35% more turns on all windings and the dcr of the windings are considerably higher. Overall this means a 31267 wired backwards will have a slightly worse noise performance but the final noise performance is most likely dominated by the first transistor stage so I doubt the effect is noticeable. The higher number of turns may mean the frequency respose at the high end is not as goo but on balance I think it will work OK.
