I think it is desirable to unwind the secondary layer by layer to find out precisely why the coil failed, as apparently failure of this type might easily take place on one of our standard coils. It is therefore interesting to find out precisely what caused the trouble. BY.{R.W. Bailey - Chief Engineer} | ||
