SM3—9 

The Ramsey Kit Warranty 

 

Please read carefully BEFORE assembling your kit. 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. 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. 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. If you believe we 
packed an incorrect part or omitted a part, 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 (1/2 hour) repair fee of $18.00, 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 l ke. 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 $36.00 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.
