This work is on a building a simple valve tester using discrete components such as transistors and diodes. The main aim of having tube tester on hand is to make sure that all valves are working properly. The tester was built with a 30V 2A transformer. It drives a 4X or 6X voltage multiplier via a "HI/LO" switch to generate 90, 125, 180 and 250 volts for supplying the test voltages for the valve under test. The HI/LO switch feeds the voltage multiplier from either the full 30V from the transformer or from the 15V tap to halve the output voltages.

CHAPTER ONE
1.0                                                          INTRODUCTION
1.1                                           BACKGROUND OF THE STUDY
A vacuum tube which is also known as a valve or tube is defined as a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied.
The type known as a thermionic tube or thermionic valve utilizes thermionic emission of electrons from a hot cathode for fundamental electronic functions such as signal amplification and current rectification. Non-thermionic types such as a vacuum phototube, however, achieve electron emission through the photoelectric effect, and are used for such purposes as the detection of light intensities. In both types, the electrons are accelerated from the cathode to the anode by the electric field in the tube.
A tube tester is an electronic instrument designed to test certain characteristics of vacuum tubes (thermionic valves). Tube testers evolved along with the vacuum tube to satisfy the demands of the time, and their evolution ended with the tube era. The first tube testers were simple units designed for specific tubes to be used in the battlefields of World War I by radio operators, so they could easily test the tubes of their communication equipment.

1.2      AIM AND OBJECTIVES OF THE STUDY
A valve tester is nothing more than a set of adjustable calibrated power supplies, a meter to measure to current and a set of sockets into which the valve under test can be inserted which is the main aim of the study. The objectives of the study are:

1. To build the system prototype
2. To provide emission readings at the recommended data book operating conditions
3. Provide mutual conductance readings, directly or indirectly
4. Test valves for internal shorts

1.3      SCOPE OF THE STUDY
The scope of this study covers building a simple valve tester using discrete components such as transistors and diodes. the tester is quite straightforward with a 30V 2A transformer. It drives a 4X or 6X voltage multiplier via a "HI/LO" switch to generate 90, 125, 180 and 250 volts for supplying the test voltages for the valve under test. The HI/LO switch feeds the voltage multiplier from either the full 30V from the transformer or from the 15V tap to halve the output voltages.

1.4      SIGNIFICANCE OF THE STUDY
This study shall provide a means of understanding how valve works and also how their test can be carried out on different types of valves. To the student involve, this study will provide a technological knowledge on how a simple valve tester can be built.

1.5      APPLICATION OF THE STUDY
This device can be used:

1. In electronics laboratory
2. By electronics hobbyist

1.6                                             PROJECT ORGANISATION
The work is organized as follows: chapter one discuses the introductory part of the work,   chapter two presents the literature review of the study,  chapter three describes the methods applied, chapter four discusses the results of the work, chapter five summarizes the research outcomes and the recommendations.
