CAD 120S MKII
stereo POWER AMPLIFIER

The stereo vacuum tube power amplifier has a great history at Cary Audio Design. The previous generation CAD 120S, Rocket 88R, and V 12R power amplifiers garnered fantastic reviews for stable power output, incredible value for the money and sound quality along with ‘Best Buy’ and ‘Class A’ ratings from magazines and reviewers worldwide. Building on this storied legacy, we are releasing the next generation CAD 120S MKII stereo vacuum tube power amplifier. This innovative stereo power amplifier is rated at 60 watts per channel in triode mode and 120 watts per channel in ultra linear mode into an 8 ohm speaker load.

Cary Audio Design’s CAD 120S TubeAmplifier is recognized as one ofElectronic House' s Coolest Components: The Best Products of 2008 (September 2008 issue).

The CAD 120S Tube Amplifier is an Electronic House 2008 Product of the Year featured in 'The Coolest Components' slide show.

The CAD 120S Tube Amplifier is introduced in the Electronic House January 2007 issue.

Full rated output power is from 17 Hz to 23 kHz with less than 1% total harmonic distortion. The output stage may be switched ‘on the fly’ from triode mode to ultralinear mode by using a front panel selector button. There are LED lights above the mode selection button to show which mode the power amplifier is working in for visual confirmation.

The vacuum tubes in each channel consist of one (1) 6SN7 for the input stage, one (1) 6SN7 for the driver stage and four (4) KT 88 output power tubes. The circuit is a Pure Balanced design with separate RCA and XLR inputs. A soft start turn on circuit is built-in for long life and easy turn on in large systems. The power supply features 1,120µF of capacitance per channel for ample reserves in demanding usages. The output transformers and the power transformer have a single cover painted to match the chassis.

The backlit front panel meters indicate the circuit bias setting for each channel and visually indicate proper operation for the CAD 120S MKII amplifier.
