| - sheet 2 - E.3/HP.25.10.35. (5) With regard to extra turns on the series winding, this is rather difficult as it involves increasing the height of the whole unit, and then it will not go into the standard case. We should like you to do a little more investigating to find out why the reverse current is worse. At the same time two amperes is not unusual in general practice.
