The stated ratings of the transformer.  1.14 kva means it is rated for about 
a kw of audio (theoretically 1140 watts with perfert power factor)  just 
call it a kw to account for some inevitable phase shift.  That means it 
should be designed to modulate 2 kw DC input.  But with the current rating 
of .198 amps, to get 2 kw DC input, you would need 10,101 volts on the 
plate.  The rated load impedance is 5500Ω.  10 kv @ 198 mills is 
51,152Ω
