Who makes this Pre-amp?


Octal based 6NS7 or 12NS7, 4 inputs, 2 outputs, tube rectified, point to point wired with top shelf parts. Remote control, at least volume control is a must. One balanced input and one balanced output a plus. HT by-pass is not necessary. Dual mono would also be nice but not necessary.

I have the Ultra 4C Preamp that came with an external tube rectified power supply.  Unfortunately, I don't think that he still offers the tube rectification anymore.  Regardless, it is a great sounding preamp and he offers customizing.  For mine, I ordered the Auricap option and a mono/stereo switch.
I have a Mapletree 2A SE with tube rectification. That’s where I got a love of the octal tube. Just want to see if I can move up with this type of pre and add a remote.
I'm looking for similar but with tone controls and a headphone jack.
Does anyone know if Don Sachs can add a headphone jack? Could the preamp circuit drive headphones? Or, do you need a separate headphone amp circuit?
