VAC, BAT, Atma-Sphere & Aesthetix all make tube preamps that are truly balanced. Most BAT models have only balanced inputs & outputs. My VAC has both types. Cheers,

Balanced vs RCA preamps
How important is it that your Pre-amp has both balanced and RCA capabilities? I’m shopping for another pre, most likely tube, and it seems to make sense with any future component that it offers both XLR and RCA. And to further complicate the search finding both these features plus remote limits the offerings for both tube and SS particularly tube.
