Hi Chip,
Also going from my memory, the most common economically available
transformer "frame sizes" in this 24-28V range, the smallest to be found is
2 amps from my memory. Which yes, is a bit large and probably "overkill"
some.
Here is a source I am familiar with and just now looked up...and have used
for many parts in the past. You are free to source from where you want,
just a suggestion.

Again hope this helps,
