Transformer-coupled tube phono pres


There are plenty of full-function pres with output transformers but how about stand-alone tube phonos?

Lonestarsouth, step-ups for LO MC have nothing to do with a transformer-coupled output.

The reason for the question has to do with a achieving a very low output impedance. With tubed unit, about the only way to do this is with transformers. (Or paralleling tubes ala CJ I guess.)
I think the K&K/Art Audio Vinyl Reference may have a transformer-coupled output.
