The inductance of a flat spiral coil can be determined by entering its dimensions in the boxes above. The "extra coil" was self-resonant and, rather than being driven by magnetic coupling, it was driven by having its bottom wire directly connected to the heavy secondary winding of the 2-coil transformer. The values for the air-gap given in the chart refer to the total gap and in the case of EI laminations the gap at the center and in each leg should be just half the value read from the chart. Flyback transformer. of the coil, the spider coil approaches the same dimensions as a flat spiral coil wound on one side of the form. The difference is the DVC sub offers more wiring options to better match and take advantage of the amplifier.
