    Default FS: Passive preamp, Pass B1 R2 with built in MM phono stage

    For sale, my passive preamp using the Nelson Pass B1 R2 complimentary JFET buffer design, direct coupled with no capacitors in the signal path.

    Two box construction with dual low noise shunt regulated power supply, preamplifier and screened umbilical connecting cable.

    The preamp uses a complimentary pair of matched Toshiba JFETs, a quality Swiss Elma selector switch and 100K stepped attenuator with Dale resistors. The inbuilt MM phono stage is built on an Elliot Sound Products phono PCB and uses a pair of AD823AN jfet input opamps.

    The preamp has one phono input, three line inputs and an earth binding post for the phono stage. Gold plated RCA input and output sockets with PTFE insulation. Silver plated PTFE insulation signal wiring.











    I'd like £185 plus RMSD postage at cost.

    Oh my god! There's nothing wrong with the bidet is there?

    “Nothing discloses real character like the use of power. It is easy for the weak to be gentle. Most people can bear adversity. But if you wish to know what a man really is, give him power. This is the supreme test. It is the glory of Lincoln that, having almost absolute power, he never abused it, except on the side of mercy".

    “You see these dictators on their pedestals, surrounded by the bayonets of their soldiers and the truncheons of their police ... yet in their hearts there is unspoken fear. They are afraid of words and thoughts: words spoken abroad, thoughts stirring at home -- all the more powerful because forbidden -- terrify them. A little mouse of thought appears in the room, and even the mightiest potentates are thrown into panic.”

    "You don't have free will. You have the appearance of free will.”

    “There's a war out there, old friend. A world war. And it's not about who's got the most bullets. It's about who controls the information. What we see and hear, how we work, what we think... it's all about the information!”
