39-116 and 39-55 Transformer - Brad Winder - 11-29-2018

Question: I know the 39-116 and the 39-55 were "sister" sets, the 39-55 being AM only and having 4 fewer tubes than the 39-116. But would a power transformer from a 39-55 still work ok in a 39-116? The 39-116 only consumed 10 more watts than the 39-55, and both use #80 rectifier tubes, and have the separate filament transformer...
