Before You Start Building - Ten-Tec 1253 Assembly And Instruction Manual

BEFORE You Start Building!

Your receiver is designed to work perfectly as soon as correct construction
is completed. If you understand typical problems BEF0RE you build, chances
are good that you won't make those classic errors which can frustrate
electronic kit builders. There are just 4 possible mistakes which will cause
your receiver not to work:
1. Installing a WRONG part.
Example: Using a 10 ohm resistor in place of 1 K (1,000 ohms)
Or, using a resistor in place of a molded inductor.
2. Installing certain parts BACKWARDS.
Example: Reversing the (+ ) and (-) sides of an electrolytic
capacitor, or pointing the flat side of a transistor
in the wrong direction.
3. Faulty SOLDER connection.
Example: "cold" connections or solder "bridges"
4. OMITTING a part, solder connection or wire.
Example: if it's supposed to be there and isn't,
we have a problem!
If a word or construction detail is unclear to you, check the glossary, or
compare the imprinting on the board to the directions, or show it to a
knowledgeable radio friend.
Installing Parts on the Circuit Board:
When we say "INSTALL" a part, we mean:
Choose correct part value
Insert in correct PC Board location
Insert correctly, if there is a right way and wrong way
such as for diodes, the audio IC, electrolytic capacitors,
and transistors.
Solder all wires or pins
Trim or "nip" excess wire lengths
