-In many classic scopes, the high voltage transformer that supplies the cathode, blanking, and anode voltages has a tendency to break down.  This is mostly because of aging of the potting material used for the high-voltage windings.  Currently the only option when this happens is to find a similar transformer from another scope.

 The same HV transformer, part number 120-0308, is used in the [[543|543B]], [[544]], [[545|545B]], [[546]], and [[547]].
 Chuck Harris, who frequents the Yahoo Tekscopes forum, has rebuilt several 120-0308 transformers with good results.
