Mosfet & npn Transistors

A set of circuit boards for construction of switching and amplifier circuits with a mosfet or npn transistor.  Adresses all learning outcomes and suggested activities in National 5 and Higher courses.
Circuits are built by screw mounting the component panels on the main circuit boards, giving a built circuit which exactly matches the circuit diagram.  Twelve component panels are supplied, including fixed and variable resistors, capacitors, switch, LDR, thermistor, potentiometer, and a bias network for building an amplifier circuit.
Bare components can be used for circuit construction if required - they mount in miniature sockets as in other JJM boards.

The Mosfet and npn transistor boards are available separately, but the system has been developed as a complete package and this is the most cost effective way to purchase the boards.
09-001 Mosfet + npn + components : £46.35
09-002 Mosfet + components : £40.00
09-003 npn + components : £39.60
