Cassette Trainer

Introduction:
|
|
|
Our sister company Audio Equipment Trainers are based
upon the popular brand solid state tape recorders
which incorporate the latest industry design features.
These trainers are specifically created to teach
cassette recorder operation, theory, repair and
servicing. Special attention is given to fault
diagnosis so as to facilitate the teaching of
troubleshooting techniques. These trainers are ideal
for use as stand alone units or can be combined with
our other audio trainers to make a complete stereo
training system.
The cassette recorder is mounted on an attractive
chassis which allows the main printed circuit board to
be exposed for ease of work. The circuit board
features a glass cover which has opening for access to
all test points so as to allow insertion of probes
while protecting the student and the circuit board.
The cassette mechanism is mounted in its original case
which has been modified so as to allow the mechanical
parts to be easily accessible for student work. The
trainer allows access to the entire factory
recommended key points for the taking of measurements,
analysis and adjustments. All controls are functional
just as on an actual cassette recorder/player.
The teaching program is designed to follow the service
procedures as recommended by the manufacturer and uses
the factory service manual in conjunction with student
job sheets. Each trainer comes with complete
courseware information as follows:
|
|
A) |
Factory service manual with
detailed circuit board schematic diagram. |

Model: II-EDU-1009 |
|
B) |
Student job sheets with fault
guide and writing diagram. |
|
A unique fault insertion system is built into the
trainer for student instruction purposes. The system
features a Schematic Block Diagram silk screened onto
an integral fault board that utilizes toggle switches
to insert the fault. Single or multiple faults may be
introduced at any time. Faults may be visualized by
means of oscilloscope to compare the wave forms of the
fault symptoms and the ideal state.
