Dan,

It would burn up! The modulation transformer is only designed to handle a
few hundred milliamps!
Impedance matching also becomes a very important factor in selecting
modulation transformers. The impedances are determined by the voltage and
current, are are vastly different in tube, and solid state circuits.
