[GreenKeys] Loop supplies

Since most of us have a love and a somewhat substantial investment of 
time and money in Teletype machines, seems like a small investment in 
a non-marginal loop supply would make sense.  The transformer 
mentioned in   Cory's post with the dual 115 volt primaries and 
secondaries looks to be somewhat ideal in that it could be wired to 
produce a 60 vac output (primaries in series in 115/120 volt 
countries). The secondaries can be wired as a center tapped output 
feeding two diodes or each winding could be used separately with 
bridge rectifiers for two independent loop supplies producing 75 to 
80 vdc each.
