Philco 46-350... capacitor with wire wrapped around it.
#7

So from a theoretical viewpoint, a winding around a conductor (which the capacitor is) serves as a current transformer. The current thru the wire is proportional to the current thru the capacitor. In this case, the effect can only be a very high frequency effect, since this is basically an air core transformer. As a transformer, there is also an inherent inductance. As this is a single turn the inductance is VERY small. I suppose there may be a common mode chocked effect here since the wire has a few twists around itself. I suspect that any improvement is wishful thinking on the part of the designer, but I did compromise and leave the loop, but around a modern capacitor, it is a much looser loop. The radio seems to work with this change. At this point the recap is about 75% completed, and the radio seems to be fully functional thus far.

Thanks for everyone's input,
Merry Christmas,
Terry
