Just saw the thread,sorry for delay.
This is how I managed this.
I got regular adapter,matched voltage,mA etc,then I got that jack(here its called Sony jack
)
with yellow line on it.
Gave it to el, tech. to wire it and that's all.
So the main deal is to find the jack/connector.
As I said,has yellow line,called Sony jack as well,google it or som,hope this helps.
