Like Colin I am somewhat shocked at the words “left over” with regard to beer and out of respect for our Belgium friends I can’t say what I think about your choice of liquid refreshment, but the word “small” sort of sticks in my throat.
Just one word of warning when making baluns though; Those damned ferrets don’t arf squirm when you wind the wire around them and they have very sharp teeth.
