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 incred bly 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 $49.00 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.
