Martin questioned my article "A review of the Guanella 4:1 balun on a
shared magnetic circuit" at http://www.vk1od.net/balun/gsc/index.htm .

Ian (GM3SEK) kindly drew my attention to incorrect reference to two of the
figures in the above article. The error was misleading, it is fixed now. My
apologies to anyone who was confused by the error.

Thanks Ian.
