Transformer driver project, many questions....

I am going to drive an AC adapter xmfr in reverse with a 12V input to get 120V out.

COIL SPECS:
Primary (low voltage) coil: 54mH, 2 Ohms (Z @ 60Hz=22Ohms)
Secondary (high voltage) coil: 2.9H, 94 Ohms (Z @ 60Hz=1187 Ohms)

Calculations at 60Hz: primary current 545mA, secondary current 101mA. The current ratio is not correct since the turns ratio is 1:10. Should I add a primary resistor to limit the primary/secondary current? I want the secondary current to be limited to 20mA when shorted. The load is a very low impedance, about 5 Ohms.

The driving circuit (5V) is a 555 with a flip flop to make it a 50% duty cycle square wave @ 60Hz...The flip flop inputs to two 4049's to provide enough current to drive the transistor base.....What should the base resistor be? How would I calculate it?

Thanks in advance everyone!
