INTRODUCTION
This is a two stage transistor amplifier with a provision for positive and negative
feedback. The amount of feedback is adjustable and with the help of this it is even possible to
make the amplifier oscillate. A 9V stabilized power is provided on the same board.
The experimental set-up has been laid down on a decorated bakelite board with an aim of
providing an easy understanding to the students. All components are well spread out for clarity
and easy repairs and replacement. The set-up is provided with a booklet, which contains its
detailed theory of operation, description, specifications, suggestions and discussion on the
various experiments that may be performed with it.
MEASURING/TESTING INSTRUMENTS REQUIRED
1. A.C. Millivoltmeter (True R.M.S. A.C. Millivoltmeter, Model: ACM-102)
2. A.F. Oscillator
3. CRO
