THE VERY FIRST AIRTIGHT ATC-1 PREAMPLIFIER

AirTight's first preamplifier model "ATC-1" serial number "001" has been returned to the Airtight factory for regular overhaul. This memorable unit was purchased by the owner in 1987 as a combo with the stereo power amplifier ATM -1 and was used by a single owner for 34 years. Still performing like the original.
