HV transformers

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 is used in the 543B, 544, 545B, 546, and 547.
