- I 71) NNW Sincerely, HEATH COMPANY Benton Harbor, Michigan 49022 11 11 1 11 111 11 I I I O Dear Customer: The Heathkit electronic product you have purchased is one of the best performing electronic products in the world. Here's how we aim to keep it that way: Your Heathkit Warranty During your first 90 days of ownership, any parts which we find are defective, either in materials or workmanship, will be replaced or repaired free of charge. And we'll pay shipping charges to get those parts to you - anywhere in the world. If we determine a defective part has caused your Heathkit electronic product to need other repair, through no fault of yours, we will service it free - at the factory, at any retail Heathkit Electronic Center, or through any of our authorized overseas distributors. This protection is exclusively yours as the original purchaser. Naturally, it doesn't cover damage by use of acid-core solder, incorrect assembly, misuse, fire, flood or acts of God. But, it does insure the performance of your Heathkit electronic product anywhere in the world - for most any other reason. After-Warranty Service What happens after warranty? We won't let you down. If your Heathkit electronic product needs repairs or you need a part, just write or call the factory, your nearest retail Heathkit Electronic Center, or any Heath a,uthorized overseas distributor. We maintain an inventory of replacement parts for each Heathkit model at most locations - even for many models that no longer appear in our current product line-up. Repair service and technical consultation are available through all locations. tNe hope you'll never need our repair or replacement services, but it's nice to know you're protected anyway - and that cheerful help is nearby.

Before you start to assemble this kit, read the wiring, soldering, and step-by-step assembly information in the "Kit Builders Guide." 2. Due to the small foil area around the circuit board holes and the small areas between foils, it will be necessary to use the utmost care to prevent solder bridges between adjacent foil areas. Use only a minimum amount of solder and use no larger than a 25 N -watt soldering iron with a small tip. Allow it to reach operating temperature, and then apply it only long enough to make a good solder connection. 3. If a small wattage, small-tip soldering iron is not available, proceed as follows: Be sure your soldering iron is cool. Wrap the large bare wire (supplied) tightly around the soldering iron tip as shown in Figure 1. Allow approximately 1/4" of wire to extend beyond the end of the soldering iron. Cut the wire end to a SOLDERING' IRON TI P F igure 1 chisel shape as shown. Occasionally apply solder to the turns of large bare wire to achieve a good heat transfer. 4. Resistors will be called out by their resistance value in 52, kn, or MS2, and color code. 5. Capacitors will be called out by their capacitance value (in pF or a uF) and type (disc, mica, Mylar, or electrolytic).
