Hello Gavin:

Based on the little bit I do know about transformers, if the physical size
difference between the two is significant, then the electrical properties
are likely to be different too.

This could mean differences in turns ratios, turns per volt, wire size,
and so on.  I think you'll be better off to look for two identical units
rather than risking the two you have, and possibly yourself.

Check around at appliance dealers and scrap yards, and you should come
up with two (or more) identical units in no time.
