| X6012 3.3.31. X.6012. COIL WITH INSIDE END OF SECONDARY CONNECTED TO COMMENCEMENT OF PRIMARY. No advantage was noted during experimental testing of this coil and we conclude that it is immaterial to which end of the primary the inside end of the secondary is connected from the point of view of coil performance.
