cables. The cables should always be the bipolar-multithread type (in
no case should rigid single thread cable be used), preferably board,
such as the cables for hi-fi connections normally available in the
specialized shops. For those who wish to use ordinary electric wire, it
is advisable to keep to the following minimum requisites:
