Thanks for comments fellows; I do not have that all H.D.transformer anymore.

Anymore ideas anyone? thanks Ali James Sweet wrote: > "alitonto" <alitonto@hotmail.com> wrote in message > news:1116162910.629050.136130@g43g2000cwa.googlegroups.com... > > I have Digitor 12 volt TV Model G7200 year 1993 from Dick Smith > > Electronics for which the H.D.Transformer is no longer available from > > spare parts.
