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. A ‘feather duster’ type cleaner will also work well for cleaning the component.
Replacing Vacuum Tubes
If it becomes necessary to replace the tubes, the same brand as installed new should be used. A complete new tube kit is available from Cary Audio Design. Although useful tube life varies depending on the nature and degree of use, under normal home use, the 845 or the 211 output tube and the 300B driver tube should last many years in the CAD 211. The 6SN7 input tubes should last even longer.
NOTE: Any current production or New Old Stock (NOS) types of 845, 6SN7 or 300B tubes will work fine in the CAD 211 Anniversary Edition amplifier. The voltages are fine for all available types.
WARNING
Make sure the amplifier is unplugged 30 minutes from the AC mains before replacing the tubes to avoid risk of shock and high heat from the 845 tube.

WARNING
Make no attempt to put the CAD 211 in service outside of the cabinet or with the cabinet open! Contact with the high voltages found inside the unit can be fatal! Remove the AC power plug from the wall and allow 30 minutes for the high voltage capacitors to discharge through bleeder resistors before attempting to change the tubes or to clean the inside the amplifier.
