New 2024 updated version of Air Tight ATM-1 (1986) and ATM-1s (2006) offers he EL-34 push-pull circut and 2 x 35 W power rating.
Reference level Opus-1 offers SH-uX core sealed in ultra-hard duralumin housing. Extended frequency range 10 - 50,000 Hz and 1.4 Ohms internal impedance looks very impressive.
The input stage of the amplifier is built on one 12AX7 lamp, the cathode repeater is built on three 12BH7.
The main feature of the Airtight ATM-2211 is the use of two independent power sources in each device. As a result, the system began to produce much less noise, and its power increased from 18 watts per channel to 32 watts per channel.
The Air Tight ATM-300R runs on 300B lamps and has a copper-coated chassis, the power figures have not changed relative to the previous model - the device outputs 2 x 8 watts.
A high-end two-stroke ATM-2 tube amplifier from the legendary Japanese company Air Tight, built on the basis of 6550/KT-88 lamps. The amplifier does not have printed circuit boards - all wiring is 100% manual and made using audiophile wires using high-quality silver solder.
Simple and elegant in appearance, the front panel is made of 8mm extruded aluminum, milled aluminum handles and a four-layer glossy body coating. The amplifier uses a new design using the legendary Mullard phase inversion lamps (such as the 6CA7 lamps).
This preamp is based on four lamps: two - 12AX7 and two — 12AU7.
The Air Tigh ATC-5s uses three 12AX7 tubes on the EQ side and two 12AT7s on the amplification side. It has two single-ended inputs for moving magnet (MM) capsules so that it can play with two cymbals or two arms. It also has three line inputs.
The ATC-3 preamp is the most affordable yet uncompromising amp from Air Tight. It will be an ideal partner for all power amplifiers from this manufacturer, especially the ATM-1, ATM-2, ATM-300 and ATM-211.
On the front panel of the device there are two large illuminated windows in which the selected curve is highlighted, in total there are five options available - RIAA, NAB, AES, FFR, FLAT. The Airlight ATE-3011 phono corrector is made on 12AX7 lamps, has three RCA inputs and weighs 12.2 kilograms.
The base of the cartridge is made of A7075 aluminum alloy, which provides precise bass and a clean sound stage, while the body is made of A6063 aluminum. The needle holder is boron, a needle with an elliptical "semi-line contact" sharpening is attached to it. The downforce is 2-2.2 g. The terminals are coated with rhodium.
The Air Tight PC-1 Supreme has an amazingly low internal resistance of just 1 ohm. Thanks to the epoch-making SH-uX coil material, Air Tight designers managed to increase the thickness of the conductor and reduce the number of coils by 40%!
