  Am I missing something, or does your statement, "I am uninterested in killing
cows" mean that you are assuming that the Hammond transformer will *always*
put out 200 mA, no matter what the load is?  It won't.  So buy it and only
draw 10 mA, it will most certainly be able to supply your 10 mA with a
comfortable safety margin.  Of course, if the 1250 VAC is too low for your ~1300
VAC requirements, then you do have a reason to not get it....
