	This is the pure, powerful triode amp you’ve waited for. It will power any speaker I know of, regardless of type or efficiency. Its sound is both triode big and triode delicate, and that’s quite a trick. The Cary 211s are one of the five or so best tube amps on the planet.
	Robert H. Levi

The CAD 211s employ a big pair of 845 output tubes run in push-pull class A to 70 watts, class A1 to 110 watts and beyond, with zero feedback. The driver tubes are a pair of 300Bs, the input tube is a single 6SL7, current source tube is a 6CA7, and there is a 1629 "cat’s-eye" tube on the front panel for power indication. 4-,8-,and 16-ohm speaker connections are provided. A detachable power cord, single-ended and balanced inputs, a brightness control for the cat’s eye, standby and power switches are all provided. The power transformer has a 300 percent duty cycle and is impregnated with silicon wax to eliminate vibration.
