Could this "4s Universal Tube Preamp" work as a phono preamp paired with a gainclone? Thanks, -jvc

Nope. A phone preamp needs a compensation network. The 4S doesn't have that.

I have built three Radi0kit tube phono preamps and they are excellent. Go for the one with the better parts. Cheap and complete. You will need a really quiet PS but they are cheap and easy to build.
