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.

AF1 specifications

Ramsey Electronics AF1 is a state-of-the-art audio frequency oscillator, renowned for its versatility and performance in various electronic applications. Designed for hobbyists and professionals alike, the AF1 is an essential tool for anyone working with sound generation, modulation, or detection.

One of the main features of the AF1 is its wide frequency range, spanning from 1 Hz to 100 kHz. This broad coverage enables users to generate tones suitable for a multitude of tasks, from simple audio testing to more complex signal modulation in communication systems. The AF1 provides a stable wave output, which is critical in maintaining audio fidelity and ensuring accurate readings in testing environments.

The AF1 employs advanced technologies to achieve its remarkable performance. One of these is its precision frequency control, which allows users to set the output frequency with accuracy. This is facilitated by the device’s inclusion of a calibrated variable resistor, enabling fine adjustments for precise frequency generation. Additionally, the AF1 features a built-in frequency counter that simplifies the process of monitoring the output frequency, providing users with a valuable tool for troubleshooting and calibration.

Another characteristic that sets the AF1 apart is its dual output channels. This allows for the simultaneous generation of two distinct frequencies, offering greater flexibility in applications requiring complex audio signals or dual-tone generation. The outputs are adjustable in amplitude, which helps users tailor their signals according to specific requirements, whether for testing speakers or experimenting with audio synthesizers.

The AF1 is also designed with ease of use in mind. The interface is intuitive, featuring a straightforward layout of dials and switches that enables quick adjustments and settings. This user-friendly approach is ideal for those who may not have extensive experience with electronic signal generators.

Constructed with high-quality components, the RAMSEY AF1 ensures durability and reliability, making it suitable for both fieldwork and laboratory settings. Its compact design allows for easy transport, fitting seamlessly into any toolkit.

Overall, the Ramsey Electronics AF1 is a powerful audio signal generator equipped with a rich feature set, including extensive frequency range, dual outputs, precision control, and intuitive usability. Whether you are a hobbyist, educator, or professional, the AF1 is a valuable asset for any electronic project involving sound generation.
