Re: Number of turns for a secondary?

This thread has made me curious as I plan on winding a larger diameter coil
soon myself. I always thought that you decreased the gauge of the wire (fewer
turns per inch) to keep the H/D ratio compatible with the number of turns
(ideally somewhere between 4:1 or 5:1 & under 1000 turns). I thought that was
why (aside from the current being carried) the larger coils always used a
heavier gauge wire. Like I said I'm just curious & I know a lot of other
factors come into play in the design. Thanks,  Jim
