@Phill Thank you for the info -
I had thought about labelling everything and a photo. I've been inside it a few times before to clean and once it fell out of the attic 1 floor down burst open and bits fell out amazingly it still worked after putting back together. Just want to make sure the PSU is safe before I give it away at the end of march lol don't want to burn down another persons home lol.
Thanks again
@Terry
