I am relisting this after a buyer backed out. Dick Olsher, in an article in positive-feeback online, describes the Air Tight ATC-2 as the ”elite of preamplification” and indeed it is. For sale is a mint condition ATC-2 line stage with the upgraded and highly desirable dark faceplate. This is a true, no-holds-barred, reference line stage. It is Miura-san’s classic tubed line stage. The many excellent reviews have all mentioned the superb transparency, amazing resolution of detail, beautiful craftsmanship, and ease of use. The ATC-2 is designed without printed circuit boards and is hand wired, point-to-point,
In addition to the faceplate upgrade, this unit comes with the with the optional premier ALPS HQPRO volume control ($1000). The preamp has several additional important upgrades, done by Roger Sheker of Audience in California. The one 12AX7 tube is replaced by a third 12AU7 tube, in order make the output impedance more manageable, and the 6X4 rectifier tube replaced by a 6CA4, for reliability and uniformity. Also, the original hardwired power cord has been replaced by an IEC socket so that any power cord can be used. The jacks on the back were replaced with Cardas jacks and the interior wiring with Audience wire. All of this brings the ATC-2 to a new level of performance.
This will come with a quad of NOS 1957 JRC5814a (12AU7) tubes.
I purchased this from another AG member last year. After I received it I sent it to Tom Tutay, the Air Tight warranty/repair representative for the United States, to have it checked. Tom told me that it was in perfect condition. It is in excellent cosmetic condition, no scratches or dings. I have listed it as 8/10 to be conservative.
The preamp has five line inputs, a tape loop, and two speaker outputs. The build quality is amazing – it is built like a tank, the volume control is silky smooth – and the faceplate and body absolutely gorgeous (pictures do not do justice.) If you don’t need a built in phono stage, this is about as good as preamps get.
I do not have the original box, but will double box for safe shipping. (Please read my feedback for comments on my ability to pack well.) Buyer pays shipping and PayPal fees.
