PARTS VERIFICATION

Before beginning the assembly process, first familiarize yourself with the components and this instruction book.

Verify that all parts are present. This is done best by checking off each item in the parts list.

IDENTIFYING RESISTOR VALUES

Use the following information as a guide in properly identifying the value of resistors.

IDENTIFYING CAPACITOR VALUES

Capacitors will be identified by their capacitance value in pF (picofarads), nF (nanofarads), or

m

F (microfarads). Most

capacitors will have their actual value printed on them. Some capacitors may have their value printed in the following

manner. The maximum operating voltage may also be printed on the capacitor.

Semiconductors

IC socket

Connector receptacle

Transformer

Carbon film

Warning:

If the capacitor is

connected with incorrect

polarity, it may heat up and

either leak, or cause the

capacitor to explode.

BANDS

Electrolytic capacitors have a positive and

a negative electrode. The negative lead is

indicated on the packaging by a stripe with

minus signs and possibly arrowheads.

Also, the negative lead of a radial

electrolytic is shorter than the positive one.
