Cross-reference and technical data for CRT line-output transformers (flybacks / LOPTs), triplers and related EHT components. Source & data on GitHub
Type any part number to start. Whatever is printed on the transformer, or the make and model of the set it came out of.
Reference data for CRT line-output transformers (flybacks / LOPTs), triplers and related EHT components. The manufacturers' catalogues that carried it are out of print or offline, and the same transformer is usually listed under several different part numbers.
Search by any part number, by the TV or monitor a part was fitted to, or by electrical characteristics. Where a part is unobtainable, the site lists others of a similar design to consider.
Every record shows its source. A published cross-reference means a manufacturer sold one part for another's application; it is not a measurement. Substitute suggestions are search results, not recommendations.
Inductance, DC resistance and inter-winding capacitance determine whether a flyback will work in a given circuit. None of those values are in this dataset. Some figures were read by machine from scanned drawings and contain errors.
Much of the reference data originates with HR Diemen, a Spanish manufacturer of replacement flyback transformers. HR Diemen is a trademark of Efiter S.L.
