Hi Daniel,Since the two primaries will be connected in series, you'll need about half the primary inductance as a single TC with the same size tank cap (everything else being the same). Using a modeling tool, model it as a single TC using your your planned primary tank cap size. Then reduce the number of primary turns (for each bipolar primary) to get 1/2 the previously calculated inductance per primary. This should get you in the ball-park...

Hi All,Does anyone know of a general rule-of-thumb for how large to wind a primary for a bi-polar coil? For example, I'll be building two coils, each with 4-inch secondaries. I was thinking somewhere around 10 inches in diameter.Thoughts?Thanks,Dan K. _______________________________________________ Tesla mailing list Tesla@xxxxxxxxxxxxxxxxxx https://www.pupman.com/mailman/listinfo/tesla
