I lost the power supply for my Presonus Tube Pre that I bought used some time ago on Reverb. I'm going to have a power supply specially made for it - does its polarity face the negative or positive? Couldn't find any spec for that on the legacy webpage.

It's AC current so there's no polarity.  It doesn't matter which wire goes to center or barrel.
