To claim your rights under this warranty:
a. Contact the dealer or distributor where you prchased the unit. Describe the problem
and ask if he has an easy solution. Dealers and Distributors are supplied with all the
information about problems that may occur and usually they can repair the unit quicker than

If it is decided to return the unit to the factory, R.V.R. will mail you a regular authorization
with all the necessary instructions to send back the goods.
c. When you receive the authorization, you can return the unit. Pack it carefully for the
shipment, preferably using the original packing and seal the package perfectly. The
customer always assumes the risks of loss(i.e., R.V.R. is never responsible for damage or
loss), untill the package reaches R.V.R. premises. For this reason, we suggest you to insure
the goods for the whole value. Shipment must be effected C.I.F. (PREPAID) to the address
specified by R.V.R.'s service manager on the authorization.
DO NOT RETURN UNITS WITHOUT OUR AUTHORIZATION AS THEY WILL BE
REFUSED.
Be sure to enclose a written technical report where mention all the problems found and a
copy of your original invoice establishing the starting date of the warranty.
Replacement and warranty parts may be order from the following address. Be sure to
include the equipment model and serial number as well as part description and part number.

II - TUBE WARRANTY INSTRUCTIONS
VARIAN POWER GRID PRODUCT LIMITED WARRANTY
Varian products are warranted to be free from defects in workmanship and materials only.
The warranty involves both calendar time and filament (or heather) operation time.
Specifically involved are: time since the product was shipped from varian time since
delivery to the user, and operation time.
WHICHEVER ELAPSES FIRST CONCLUDES THE WARRANTY.
The warranties are determined by the codes shown in the price schedule.
TIME SINCE TIME SINCE TIME SINCE
SHIPMENT SHIPMENT HEATER-ON
Code from EIMAC To The User Time
T 36 MONTHS 24 MONTHS 10.000 HOURS
R 24 MONTHS 12 MONTHS 5.000 HOURS
P 24 MONTHS 12 MONTHS 4.000 HOURS
N 24 MONTHS 12 MONTHS 3.000 HOURS
K 24 MONTHS 12 MONTHS 1.000 HOURS
L LIFE TESTED AT FACTORY IN LIEU OF AN OTHER WARRANTY
12 24 MONTHS 12 MONTHS
The last category is for hardware or accessory items whwre only calendar time is involved.
An Original Equipment Manufacturer (OEM) or an authorized Varian Distributor can hold
an item in his stock for 12 months and the end user still receiver full warranty. As an
example, warranty code T is for 36 months from the date of the shipment from EIMAC, or
24 months from the date of delivery to the user,or 10.000 hours of filament-on time,
whichever elapses first.
A product which fails (because of faulty workmanship or materials) in the first 10% of the
warranty-time hours will be heither replaced at no charge by Varian or 100% of the
purchase price will be credited through the original authorized Varian Distributor or OEM.
If a failure occurs in the remaining 10-100% of the warranty time hours a prorated
adjustment will be calculated and credit issued. This can only be done through the original
OEM or authorized Varian Distributor
A prorated credit is calculated as follows:
Warranty (hours) - Use Time (hours)
= % Credit
Warranty (hours)

Date: 25/07/03 R.V.R. Elettronica S.r.l. (BO) VJ10000-TR - R.F. Tube Amplifier
9
Thus for failure Code N (3000 hours) if failure occurred after 600 hours and was found to be
workmanship or materials related:
3000 - 600
= 80%
3000
Tubes being returned on a warranty claim are normally sent to authorized Varian distributor
or OEM from whom originally purchased. If returned directly to the Varian plant of
manufacture, the authorized Varian Distributor or OEM from whom purchased should be
notified in case there are some special instructions.
All products returned on a warranty claim must be shipped via prepaid freight and include a
completed copy of a service report form, a copy of which is included with every shipped
product. A warranty claim cannot be processed without this form. A copy of the original
invoice, bill of sale, or other purchase document should be included with the executed
service report form to establish purchase date and price.
The original Varian shipping carton and packing material should always be used for any
warranty claim return. Shipping damage because of poor packing will normally preclude
any warranty adjustment since the damage will usually make any testing or measuraments
impossible.
PARCEL POST SHOULD NEVER BE USED FOR SHIPMENT OF TUBES.
