High Voltage Transformers
Transformers with 1 or more Secondary Voltage =>100 Volts


Most part numbers link to a photo and (S) following a number indicates photo is of a different similar looking transformer.
Photos, determining spec's of unknown transformers, etc. is time consuming & often left until someone makes an enquiry so e-mail if more information is needed.  (M) following manufacture name indicates spec's are manufactures, otherwise spec's are based on core size and other parameters commonly used to determine unknown transformer spec's. Column SC is a core size code that's explained along with more about the spec's listed for unknown transformers in my Notes Regarding Transformer Spec's.
