Description

This trainer has been designed with a view to provide practical and experimental knowledge of a general circuit of IC based Tape Recorder on SINGLE P.C.B.

• The complete circuit of a Tape recorder is printed on a single P.C.B.
• Fault creation facilities are provided by removing jumpers and by

  changing parts.

• About more than 10 faults can be demonstrated on this trainer.
• The main ICs are provided on sockets to provide a facility to check

  similar ICs and also to create the faults by inserting faulty ICs in the

  sockets.

• Explanation, Observation, Alignment and adjustment of Internal and

  external controls is possible due to single P.C.B.

• Easy identification of different parts and Mechanism at a glance.
• Easy measurement of voltages and observation of waveforms at any

  point. Also typical voltages and waveforms are provided.

• The whole circuit of the tape recorder is explained section wise in

  detail in the manual.
