WELCOME THANK YOU Dear Cary Audio Customer: I am so pleased and excited about the Cary Audio Design CAD 120S stereo vacuum tube power amplifier. I have spent countless hours designing and refining this very special vacuum tube power amplifier. The CAD 120S started life in September of 2006 as a 60 watt ultra-linear push pull amplifier. Billy Wright, my business partner, was concerned that we needed more output power for difficult loudspeaker loads.
WELCOME PRODUCT FEATURES The stereo vacuum tube power amplifier has a great history at Cary Audio Design. The previous generation Rocket 88 R and the 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 CAD 120S stereo vacuum tube power amplifier.
WELCOME UNPACKING AND INSTALLATION This section describes the unpacking and installation procedures for your new component. Unpacking All Cary Audio Design shipping cartons have been specially designed to protect their contents and special care has been taken to prevent damage under normal shipping conditions. Mishandling should be evident upon inspection of the shipping container. If shipping damage is found after visual inspection, take care not to destroy the evidence.
SPECIFICATIONS Operating the CAD 120S is a simple procedure. It is designed for long term stability in virtually any home operating environment. However, if the unit is operated outside the parameters outlined in this owner's manual, damage may result. Please read this manual carefully before putting your new CAD 120S amplifier into operation. The following section describes the CAD 120S amplifiers’ basic specifications. The specifications are subject to change without notice or obligation. ................
CONTROLS AND DISPLAYS FRONT PANEL 1. POWER • Press once to turn the power ON. • Press again to turn the power OFF. 2. LEFT CHANNEL BIAS • Indicates a proper DC current of between 130 to 150 ma. 3. RIGHT CHANNEL BIAS • Indicates a proper DC current of between 130 to 150 ma. 4. MODE • Press this button to change between Triode and Ultralinear modes. TOP PANEL The following illustration shows the tube placements on the CAD 120S.

OPERATION Your new CAD 120S power amplifier is ready for operation after the speaker, interconnect cables and the vacuum tubes have been installed into their proper sockets. Refer to the labeling on the chassis for placement and proper tube installation. SPEAKER BINDING POSTS The CAD 120S will drive loudspeaker loads from as low as 2 ohms to a high of 16 ohms without any adjustment. Please remember to keep the proper phase on each channel when connecting the loudspeaker cables.
OPERATION cycle and power loads in the neighborhood change, the bias reading will fluctuate a bit. This is normal and therefore not critical. Another word about the meter readings, the louder you play the CAD 120S the more current it will draw. Playing loud, especially in the ultra-linear mode will peg the meters at 200 ma. This is normal and there is a protection circuit built into the metering circuit to prevent damage to the analog meters.
SERVICE AND CARE CARE AND CLEANING The cabinet housing and front panel of the CAD 120S may be cleaned with a soft cloth and Windex or a window cleaner. The frequency of cleaning will be governed by how many hours the CAD 120S is operated and by the cleanliness of the operating environment. FACTORY SERVICE Careful consideration has been given to the design of your CAD 120S to keep maintenance problems to a minimum.
