Installation

This section describes the unpacking and installation procedures for your new amplifier.

Unpacking

All shipping containers 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. If necessary, document the damage with

photographs and contact the transport carrier immediately. Carefully remove your new CAD-

805 Anniversary Edition from its packing carton and examine it closely for signs of shipping

damage. It is recommended to save all original packing cartons and crates to protect your

amplifier from damage should you wish to store it or ship it for after-sales service.

Warranty Card

IN THE USA: If you are the original purchaser of a new unit from an AUTHORIZED CARY AUDIO

DESIGN DEALER, please fill out the enclosed warranty registration card and return it within 15

days of purchase or register online at www.caryaudio.com. Cary Audio Design suggests that you

keep your original packing cartons in case you need to ship the amps. Warranty restrictions

apply. Consult the warranty section of this manual for details. Keep a copy of your original sales

receipt for proof of purchase if you need service during the warranty period; we will require a

copy to validate the warranty. The warranty is for the original purchaser only and does not

transfer to any subsequent owner.

OUTSIDE THE USA: Your local Authorized Cary Audio Design Distributor will make his own

warranty policy for your country. Please check with them for the terms of warranty for your

new amplifier.

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.

Page 5

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! _

Page 8 shows correct tube placement positions, 300B tube bias settings and ‘Cat Eye’ tube

brightness adjustment. Page 9 shows 300B tube pin configuration. 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 manufacturers

warranty.

_WARNING! _

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 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.

Cleaning and Care of Finish

The chassis may be cleaned with a soft towel and Windex ® or a similar gentle window cleaner.

The frequency of cleaning will be governed by operating environmental cleanliness. Spray the

cleaner on the towel, not on the amplifier! Avoid abrasive cleaners! Feather dusters are good

for cleaning the amp.

Page 6

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.

Factory Service

Careful consideration has been given to the design of your CAD-805 Anniversary Edition to

keep maintenance problems to a minimum; however, it is possible that some problems may

arise which cannot be cured by tube substitution. If after reading the Troubleshooting Guide on

page 7 you still have a problem, contact our Customer Service Department to describe your

problem in detail. Do not return the amplifier to the factory without a Return

Authorization Number from the Customer Service Department. Cary Audio

Design will assume no responsibility if the transportation company refuses to pay damage claim

due to your improper packing or lack of insurance should the unit be lost in shipment from you

to us.

Non-Warranty Repairs

Cary Audio Design will provide repair service for its products charging on a time and

expense basis for the repairs. Contact Cary Audio Design at 919-355-0010 from 1 to 5

PM East coast time for an RMA number so that your unit may be serviced.

WARNING!

Make no attempt to put the CAD-805 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.

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.

WITH THE AMP OFF: Insert the _” bias meter plug into the bias jack on the back of the

amplifier chassis. Connect the bias cable red alligator clip to the positive (+) connection

on your meter. Connect the bias cable black alligator clip to the negative (-) connection

on your meter. Check the 300B tube bias current reading and adjust for a 60 mA

reading on the Volt Ohm Meter (VOM) or DC current meter if the reading is different

than 60 mA. Check and readjust to 60 mA again after the CAD-805 amplifier is warmed

up for 10 minutes. Remove the _” plug from the bias jack and enjoy the music!

Note: Bias is factory preset to 60 mA. Bias should be reset when

installing a replacement

Set the bias to 60

milliamperes, dc ampere scale.

300B Tube pin layout for CAD 805 Anniversary Edition

The LARGE pair of 300B tube pins should be installed toward the front of the CAD-805

Anniversary Edition amplifier tube socket. 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. If you have any doubts about this, have the

300B tube installed by your dealer. If you will look carefully at the pins and install the

large pins to the front of the socket all will be fine! These 300B tube pin

installation instructions are valid for the 805 Anniversary Edition only.

Earlier versions of the 805 amplifier had the 300B tube installed with

the pins in a different position. Look carefully at the tube pins and the

socket holes before installing the 300B tube in earlier model 805

amplifiers.
