This is the Analog IC DIP-Only Design Kit #1. This great kit has various quantities of popular Analog ICs in the DIP (Dual-Inline-Package - they have leads). You will get the LM324, the LM555, the LM741 (World's most popular Op Amp), the LM1458, Audio Amplifiers, (2) ea.  Adjustable & Fixed Voltage Regulators, various NPN & PNP Transistors, FETs, Power Transistors, Zener & Signal & Power Diodes, Resistors, Ceramic & Aluminum & Tantalum Capacitors, Inductors, Crystals & Crystal Oscillators, Trimpots, LEDS, a miniature Speaker & some Electronic Hardware to interface your circuit to the outside world. There are NO SMT components in this selection; all components are Thru-Hole.

To further help you design your circuit, you also get 2 different sizes of IC Sockets, some Headers, some RCA Phono plugs, a 9V Battery Clip, and two 162-hole Plated Thru-Hole Printed Circuit Boards. The PCB was designed by us and has 4 mounting holes, is 1.1" x 2.0", is made of FR-4 epoxy-glass and is .062" thick. This is a NightFire Electronics LLC special.

There are enough different parts to build many different types of Analog circuits. Parts may vary slightly from photo due to the availability
