This is the Audio FET & Op Amp IC Design Kit #3.It includes 8 pieces of the very popular MPF102 FET and 4 pieces of the Texas Instruments LF351 FET Op Amp in a DIP-8 package. These are two very popular Audio semiconductors on the planet and have been found in countless Audio schematics. This kit also includes different common values of 1/4 Watt, Carbon Film, Leaded Resistors, NPN & PNP Transistors, Ceramic & Aluminum & Tantalum Capacitors, Signal & Power & Zener Diodes, Pushbutton Switches, Electret Microphones, LEDs, Trimpots, a 9v Battery Clip, IC Sockets, and a miniature Speaker. You also get some Electronic Hardware to connect your circuit to the outside world.

To further help with your circuit development, you also get a 162 plated-thru hole PCB and some IC sockets. This PCB has 4 mounting holes, is 1.1" x 2.0", and is double-sided. With these parts, you can make numerous circuits such as active filters, audio pre-amps, signal conditioners, function generators and much more. Search the web for incredible circuits to build. We supply the parts, you supply the ingenuity.
