For 48V transformers use two 24V ones. Put the 24V windings in series and the mains windings in parallel. It's preferable if they are the same type and rating, but no problems if they aren't as the rating is the same as the smallest one.
Yet another possibility are 100V line transformers, intended for PA speakers. These have multiple low voltage taps to play with.
