For sale: Audio Research SP9 MKIII tubed pre-amp with modifications by Steve Huntley of Great Northern Sound (651/351-5355). Please Google the site for details. Serial #97237036. This unit is in very good cosmetic shape - there are some slight marks behind the rack mounting holes, but as you can see the unit looks good. Stock, this pre-amp is decent, but after Steve's mods it has that tube magic and really lives up to its full potential. The SP9 was one of Steve's favorite AR pre-amps to upgrade because the design is simple, it has only two tubes to replace or roll, and it offers one of the most signifcant "before" and "after" improvements once the mods are done. This is a fully functional preamp with a built-in phono section, six additional pairs of inputs, two recorder outputs, two Main outputs, (extra Cardas outputs), and an IEC power connector so that you can match with your favorite cord. Inside you will find upgraded parts used throughout.

I am including a set of JJ Cryo-Tubes, which will be carefully taped underneath the top cover plate. If you have Mullards, you will enjoy this even more. Original box included. I will carefully ship this unit via UPS, fully insured, to anywhere in the Continental U.S. for a flat $25. Or, if you live in Brooklyn and can get to the Naval Yard, you can pick up for free. Thank you and e-mail if you have questions. PayPal payment please add 3% fee to the asking price. Please view my feedback and purchase with confidence.
