Need help finding power supply for Antminer S15

I've got three S15 miners, but two of their power supplies crapped out on me last November. I sent them to myrig for repairs, but they couldn't fix them. So here I am with two miners and no power supply. I've searched everywhere and can't find any APW8 power supplies that run between 16.32V and 20.04V. While I was browsing, I noticed the APW9, which is rated at 14.5V to 21V. It seems to have the same connections as the APW8, but it has two power input ports. My question is, can I use the APW9 with an S15 miner? And why are there two power ports? Do I need two 240V lines for each power supply if I decide to go that route? If all else fails, where can I actually purchase an APW8 that meets the 16.32V 20.04V range?

Have you tried to ask ZeusBTC for repair? Or stocks for this unit? You can try ask ZeusBTC and maybe they can repair this PSU or maybe they have a few stocks of them. Check them here https://www.zeusbtc.com/ASIC-Miner-Repair/
