How can I add a headphone output to Tubelab SSE

[wcakey]

I would like to add a headphone output to my Tubelab SSE amp suitable to run Sennheiser HD598. Has anyone done this? Does anyone have a circuit they are willing to share or a pre-built board that would work with the SSE?

I did some experimenting with my UNSET and headphones, also tried the same circuit with my SSE. Both sounded good.

Thank you. It may sound ridiculous but I finally remembered that I had already built two Pete Millett headphone amps several years ago and had them stowed away on a shelf. Since I only needed the headphone amp to connect to a separate DAC, I realized that I didn't have a problem after all.
