Transformers are fun. The exception is for safety or ultra low leakage applications, in which case you often also avoid toroidal transformers (the primary wires have to get out via the secondary winding) and stick to split bobbin C or EI types too. You can't beat vintage design techniques, apparently. :) I have several floor-units for my guitar that are fed LV-AC and in fact, all-too-frequently, someone complains that "it stopped working" and it turns out that they lost the original AC PSU and tried using a DC PSU of the same voltage.   I have toyed with the idea (but I'll never get around to it  ) of adding some stuff to one of my units but I wouldn't want to add extra load to the internally rectified DC and so I would also look at separate rectification and upgrade the AC supply...so I can kinda relate to what the OP might be doing.
