Colour TV Trainer.
Colour TV trainer is an ideal training
equipment to teach the operation of colour TV receivers. The complete
circuit of colour TV receiver is printed on single PCB. section wise
coloured printing on PCB helps in easy understanding of function of
different blocks. More than 50 test points allow the analysis and
monitoring of the signals in different sections. It safe to operate
because all the test points are protected against accidental short
circuits. By using the fault simulation method, it is possible to
introduce the most common breakdown and their rectification. Technical
manual includes circuit diagram with component list of each section.
Test point details with typical voltages and wave forms are provided in
the manul. The Trainer has been specially designed with sliding main
board with locking facility. The detachable CRT Unit is another feature.
It can also be used as a normal desktop Colour TV receiver.
