ELECTRONICS EQUIPMENT REPAIR COURSES
GENERAL
These courses involve Analogue Electronic Circuits and Components. These Circuits and Components are used in Amplifiers, Power Supplies, Stereos, Hi-Fi Systems, Radios, etc. They are also used in a Computer's Power Supply Unit and to a lesser degree in the main Computing Circuitry. Electronics Equipment Repair l and 2 are available and each course incorporates approximately 50% practical "Hands-On" experience.
ELECTRONICS EQUIPMENT REPAIR I
Aim:
To enable participants to build, test and fault-find Analogue Electronic circuits Part 1 level.
