[Amps] big old plate transformer

[Ed Heimbach]

 Kenyon model s13342.
 dual primary, center tap sec. 1400-0-1400.
 any idea if it is O.K. to use this at full voltage (2800) in a full wave bridge power supply?
 If I had to guess, I would say this transformer is 60 to 70 years old, my fear is that the insulation may not handle the higher voltage across the secondary if hooked up this way.
 Any Ideas?
