PRODUCT OVERVIEW
After ten years of continuous production we are proud to offer the CAD 805 Anniversary Edition.
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.
Please read this manual carefully before operating your new CAD 805 AE power amplifiers.
The CAD 805 Anniversary Edition offers 50 watts per channel, Pure Class A Single Ended Triode
Mono Blocks with dual 6SN7 input stage, 300B driver stage tube, includes both 845 and 211
output tubes. It offers a user selector switch for the output tube, a Jaguar Anthracite black
chassis and top plate with clear coat finish, and an anodized aluminum front panel with a ZERO

OPERATION
PHYSICAL PLACEMENT
The CAD-805 Anniversary Edition is designed for use in homes. It must be protected from the
elements and temperature extremes. For example, avoid placing the unit in extremely hot
locations such as near radiators or other heating units. Its location among the user’s audio
components is not critical; however, certain precautions must be taken. Avoid moisture, direct
sunlight, and dusty areas.
POWER REQUIREMENTS
The CAD-805 Anniversary Edition is designed to operate from house current AC mains. The
design voltage is 117 Volts AC at 50/60Hz (Foreign units 234 Volts AC at 50/60Hz).
SPEAKER CABLES
The speaker cables from the output posts of the CAD-805 Anniversary Edition to the speaker
system can be any length that your setup requires. Select speaker cables of sufficient size to
preserve the outstanding performance capabilities and sound quality of your new power
amplifiers.
Heavy duty #14 gauge wire is suitable for distances up to 15 feet; #10 gauge is good for 25-30
feet. Most audio dealers have high performance speaker cable in stock for this purpose. We
strongly urge you to try several types to find the best ones for your combination of components
and speakers.
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.
Operation
Your new amplifier is ready for operation after the speaker cables, interconnect cables and the
tubes have been installed. Choose either the 211 or the 845 output tube with the top panel tube
selector switch, according to the actual one installed. Only change this switch setting with the
amplifier OFF.
WARNING
FAILURE TO 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.
8
OPERATION
OFF/ON POWER TOGGLE SWITCH
Push the AC toggle switch toward the rear, to the “ON” position. The 6SN7 input tubes, 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 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.
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-805. The 6SN7 input tubes
should last even longer.
NOTE
Any current production or New Old Stock (NOS) types of 211, 845, 6SN7 or
300B tubes will work fine in the CAD-805 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 211 or 845
tube.
