Operation - Cary Audio Design CAD 211 AE Owner's Manual

INSTALL THE TUBES CORRECTLY WILL DAMAGE THE UNIT. Watch the tube pins
carefully on the 300B tube during installation as it is possible to force the tube to plug in
'wrong' during installation. The 300B tube has no 'safety key' center pin on the tube to
prevent incorrect installation. It has two large pins and two slightly smaller pins. Please
look carefully at the tube pins and the tube socket holes to note the two different size
connections prior to installation. Incorrectly plugging in the 300B driver tube will possibly
damage the amplifier and is not covered by the manufacturer's warranty.

OPERATION _____________________________________________

Your new amplifier is ready for operation after the speaker cables, interconnect cables and the tubes have been
installed.
On-Off Power Switch
Push the AC toggle switch toward the rear, to the "ON" position. The 6SL7 input tube, 6CA7 phase inverter,
1629 Cat Eye tube and the 300B driver tube will light up in this setting.
Standby Toggle Switch
Push the toggle switch toward the rear of the unit to operate. The installed output tube will light up.
Break In Period
The tubes, capacitors and the output transformers take approximately 100 hours of music playing to fully settle in
for peak performance. Small imperfections in the tube surfaces will 'boil off' during the break in period as well. The
amplifier will sound good right out of the box but it will improve as break in occurs. After the first couple of hours
you will notice increased depth and tighter bass. This break in period is true with most high performance audio
amplifiers.
