Hi:
I sincerely looked online (2 hours looking) for the star shaped converter that you have mentioned.
I did Google searches, looked on ebay, Amazon, etc. and tried my best.
The only thing close that I found was a man mentioned in a post that the one star shaped converter outside of the house is illegal to mess with that and it's not available to the public to purchase.
Maybe other members will know where to look.
