WTB Williams transformer 15B-6797

[DRANO]

I recently picked up an inexpensive Stellar Wars project.
It's missing a few things

Chief among them is the main transformer.
I think these were a common part from system 3-6 and I'm pretty sure I've got the correct part # 15B-6797
This one is typically mounted in the game's head cabinet.

Let me know what you've got lying around?

Thanks.
