INTRODUCTION____________________________________________________ Congratulations! You have just purchased one of the most outstanding amplifiers ever made. After 17 years of continuous production we proudly announce the CAD 211 Founder’s Edition! Operating the amplifier is a simple procedure. Each unit is designed for long term stability in virtually any home operating situation. Note that if the unit is operated outside the parameters outlined in this owner’s manual, damage may result.
SPECIFICATIONS ___________________________________________________ This section describes the basic specifications of the 211 FE amplifier at the time of printing. Specifications are subject to change without notice or obligation. ........................................................................................................................................................................................................................

INSTALLATION _____________________________________________________ This section describes the unpacking and installation procedures for your new component. Unpacking All Cary Audio Design shipping crates 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.
Interconnect Cables Signal input connection is made via the RCA input jack on the rear of the amplifier located next to the output binding posts. The input interconnect cables from the output of the preamplifier can be any length your installation requires. A shielded high quality interconnect cable is important to reduce chances for hum or interference. Ask your Authorized Cary Audio Design audio dealer for advice. WARNING! Page 10 shows correct tube placement positions, and 300B tube bias settings.
SERVICE AND CARE ________________________________________________ The chassis may be cleaned with a soft towel and Windex® (or a similar window cleaner). Spray it on the cleaning cloth to moisten it, not on the component. Do not use solvents or harsh chemicals as they may remove the labels from the chassis. The frequency and need of cleaning will be governed by operating environmental conditions. Avoid letting the component become dusty or wet.
CAUTION Never remove or insert the AC plug when the unit is on or the AC power switch is in the “ON” position. Obstruction of the top portion of the amplifier will result in the tubes overheating. TROUBLESHOOTING GUIDE ________________________________________ SYMPTOM CAUSE REMEDY Hum or “Buzzing” in speakers Ground loop Install 2-pin adapter on AC cord to float the ground 300B tube with high plate current too high Check bias of 845’s.
Diagrams ___________________________________________________________ Bias Pot Bias Jack Set the 845 tube bias to 100 mA DC Current < 845 Tubes > 6CA7 Tube Power ¼” bias plug 300B 300B 6SL7 Tube Standby The 211FE is equipped with a built in bias meter on the front of the chassis. The adjustment pot is located at the back of the chassis along with a bias jack for an external meter. Check the 845 tube bias current and adjust for a 100 mA reading. The meter is marked “SET” at the 100mA mark.
300B Tube Pin Layout The LARGE pair of 300B tube pins should be installed toward the front of the CAD 211 FE amplifier 300B tube sockets. LOOK CAREFULLY at the tube pins to be sure that you insert them correctly. It is possible to force the tube pins into the socket the wrong way if you are not careful! If you install the tube wrong you will probably damage the amplifier and the tube. This damage will not be covered by the manufacturers warranty for a new amplifier.
