I have an entire DDE 1.2/PS5 combo I'm not using, but I wouldn't want to sell just the PS5 and be in the same boat.
As I mentioned in your other thread, I'd contact Mark Schifter at AV123.com. He was the man behing AA, and I believe his Perpetual Technologies DACs use the same type of PS. He may have some power supplies on hand that will work for you.
