        This will improve the audio quality of the equipment it is to be used in by allowing the flux density
        to be very low and the wire guage to be larger than would otherwise be the case.

low resistance windings for the VP24V7 and VN24V7 supplies.

This will improve the audio quality of the equipment it is to be used in by
allowing the flux density to be very low and the wire guage to be larger than
would otherwise be the case. The sizes given are maximum finished sizes.
                                                                                                                                                                                   100mm
There is no merit in attempting to reduce the size much below the maximum
sizes specified. Audio quality will be improved by making the transformer as
large as possible.
