K&K Raleigh Extreme Differential Preamplifier V. III

K&K Raleigh Extreme Differential Preamplifier, MK III version purchased assembled and tested, brand new from Kevin Carter.   Upgrades/customization include all-copper wiring, Vampire RCA jacks, and all-single-ended outputs and inputs.   The stepped attenuator upgrade employed the use of Vishay nude resistors on the entire unit ( this upgrade alone was nearly $1K).   Very light use, original 6H30 tubes in unit, owner's manual.  The Price when New is verifiable on the original receipt. I have too many preamps and have been using one with a built-in phono stage, so this one needs a new home.   See K&K Audio website for more info if desired. (Note: in the preassembled version the second board which appears to the left of the main one is there, but Kevin installed it underneath the main one, so the boards are stacked, I think for the shortest signal path).
