Nelson Pass B1 Buffer

Looking for a Nelson Pass B1 Buffer! I will probably just buy a board from NP himself and build one if I can't find something fun that someone doesn't want anymore. I'm finishing the auxiliary wiring on my Balanced Zen Line Stage and it's fantastic, but more gain than I need for my powered Martin Logans, and I'm having a bit of a impedance mismatch with a totally passive pre; input impedance of 14,000 Ohms.
Let me know what you have!

If you're running fully balanced, you'll need two.

Depending on the tube and caps used, this buffer sounds very good and is transparent(scroll to bottom): http://www.doddaudio.com/products.html
It's designed to work off of a battery, but you can also use a 12v 2A power supply. I'm using a 4.5A power supply for two modules."He who fights with monsters should look to it that he himself does not become a monster.

Only running SE these days with the line level inputs on the Martin Logans; no need for balanced configuration.
I have been chatting with Gary about his buffer, but I do like the B1 from experience. I thought it's be fun to mount a buffer in my current passive preamp, but the Dodd buffer is a lot more heat and current. -

Now that I have this B1 buffer, anyone want a multiple input passive preamp? PM me as it's a great unit, I just don't need it anymore.
