[Amps] AIR DUX rating

Hello,
  I have an old B&W tank coil.  Its about 22uh,  10 inches long, 4 tpi
of
number 12 guage wire with lexan insulators.  Spacing is 1/4" center to
center

 Dimensions are approximate except for tpi which is 4.  If I recall
correctly,
the id is 2.5 inches.

 What is the approximate power handling capability of this coil in a pi
output
tank circuit?

Thanks in advance.

Lynn, NO9Z
