Adding headphone out to diy tube preamp?

[Rockinrob86]

I recently built a VTA SP8, and would like to add a headphone out.

It has an output impedance of 1k ohms and I use 32 ohm grado headphones

Could I just get a transformer with a 1k primary and a 32 ohm secondary, and put a switch to select between my output jacks or the transformer?

It seems like nothing is ever that simple...

I also thought about adding something like a CMOY parallel with the line stage, or after the line stage if that would work better, also on a switch.

Ideas?
