The Ramsey Kit Warranty

 

Please read carefully BEFORE calling or writing in about your kit. Most problems can be 
solved without contacting the factory.

 

Notice that this is not a "fine print" warranty. We want you to understand your rights and ours too! 
All Ramsey kits will work if assembled properly. The very fact that your kit includes this new manual 
is your assurance that a team of knowledgeable people have field-tested several "copies" of this kit 
straight from the Ramsey Inventory. If you need help, please read through your manual carefully. 
All information required to properly build and test your kit is contained within the pages!   

1. DEFECTIVE PARTS:

 It's always easy to blame a part for a problem in your kit, Before you 

conclude that a part may be bad, thoroughly check your work. Today's semiconductors and passive 
components have reached incredibly high reliability levels, and it’s sad to say that our human 
construction skills have not! But on rare occasions a sour component can slip through. All our kit 
parts carry the Ramsey Electronics Warranty that they are free from  defects for a full ninety (90) 
days from the date of purchase. Defective parts will be replaced promptly at our expense. If you 
suspect any part to be defective, please mail it to our factory for testing and replacement. Please 
send only the defective part(s), not the entire kit. The part(s) MUST be returned to us in suitable 
condition for testing. Please be aware that testing can usually determine if the part was truly 
defective or damaged by assembly or usage. Don't be afraid of telling us that you 'blew-it', we're all 
human and in most cases, replacement parts are very reasonably priced.   

2. MISSING PARTS:

 Before assuming a part value is incorrect, check the parts listing carefully to 

see if it is a critical value such as a specific coil or IC, or whether a RANGE of values is suitable 
(such as "100 to 500 uF"). Often times, common sense will solve a mysterious missing part 
problem. If you're missing five 10K ohm resistors and received five extra 1K resistors, you can 
pretty much be assured that the '1K ohm' resistors are actually the 'missing' 10 K parts ("Hum-m-m, 
I guess the 'red' band really does look orange!")  Ramsey Electronics project kits are packed with 
pride in the USA. If you believe we packed an incorrect part or omitted a part clearly indicated in 
your assembly manual as supplied with the basic kit by Ramsey, please write or call us with 
information on the part you need and proof of kit purchase. 

3. FACTORY REPAIR OF ASSEMBLED KITS:

  

To qualify for Ramsey Electronics factory repair, kits MUST:     
1. NOT be assembled with acid core solder or flux. 
2. NOT be modified in any manner. 
3. BE returned in fully-assembled form, not partially assembled. 
4. BE accompanied by the proper repair fee. No repair will be undertaken until we have received 

the MINIMUM repair fee (1/2 hour labor) of $25.00, or authorization to charge it to your 
credit card account. 

5. INCLUDE a description of the problem and legible return address. DO NOT send a separate 

letter; include all correspondence with the unit. Please do not include your own hardware 
such as non-Ramsey cabinets, knobs, cables, external battery packs and the like. Ramsey 
Electronics, Inc., reserves the right to refuse repair on ANY item in which we find excessive 
problems or damage due to construction  methods. To assist customers in such situations, 
Ramsey Electronics, Inc., reserves the right to solve their needs on a case-by-case basis. 

The repair is $50.00 per hour, regardless of the cost of the kit. Please understand that our 
technicians are not volunteers and that set-up, testing, diagnosis, repair and repacking and 
paperwork can take nearly an hour of paid employee time on even a simple kit. Of course, if we find 
that a part was defective in manufacture, there will be no charge to repair your kit (But please 
realize that our technicians know the difference between a defective part and parts burned out or 
damaged through improper use or assembly). 

4. REFUNDS: 

You are given ten (10) days to examine our products. If you are not satisfied, you 

may return your unassembled kit with all the parts and instructions and proof of purchase to the 
factory for a full refund. The return package should be packed securely. Insurance is 
recommended. Please do not cause needless delays, read all information carefully.
