I just opened up a ZJ Electronics Beverage Box that I was thinking of using
at the feedpoint of a K9AY loop. To my surprise, it appears to use a very
small encapsulated 9:1 transformer and an almost invisible MMIC
amplifier. Is it worth retrofitting this with a larger toroid transformer
with the right turns ratio and isolated primary and secondary, or is the
amplifier design dubious enough so that I might as well junk it?
