Tube Replacement; Factory Service - Cary Audio Design CAD 808 Owner's Manual

The tubes, capacitors and output transformers take approximately 100 hours of music
playing to fully settle in for peak performance. The Rocket 88 R will sound good fresh
out of the box. However, after the first couple of hours you will notice increased depth
and tighter bass. This break in period is normal for tube based components and with
high performance audio components.
MAKE SURE AMPLIFIER IS UNPLUGGED FROM AC MAINS
The chassis of the Rocket 88 R may be cleaned with a soft rag and Windex (or a similar
window cleaner). A dry feather duster is also good for cleaning the chassis.
If it becomes necessary to replace the tubes in the Rocket 88 R amplifier, a matched set
of tubes of the same brand should be used. A new tube kit is available from your Cary
Audio dealer. You should get 2-5 year's from the output tubes and even more years of
use from the 12BZ7 and
Careful consideration has been given to the design of your Rocket 88 R amplifier to
keep maintenance problems to a minimum. However, it is possible that some problems
may arise which cannot be cured by tube substitution. At this point we suggest that you
contact our Customer Service Department from 1 to 5
number 1-919-355-0010, 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 a damage claim due to improper packing or lack of insurance
should the unit be lost in shipment.
