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.

Qualifications:city guilds

  1. City & Guilds of London Institute Technology, Components and Circuits (Examination No. 7267-421). This examination consists of 1 written paper and 5 practical assignments. The qualification can be used as part of the requirement for City & Guilds Diploma in IT Systems Support (7267-24).
  2. On completion of the Course, having been successful in an examination, the participant will receive a Hi-Tech Training Certificate.
