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
