Preface

This service manual covers the Tandberg tape re-
corder models 74 - 72 and 74B - 72 B.
The model 74 is a complete quarter-track, three
speed stereo, record. and playback unit with two
heads. It is equipped with separate record and play-
back preamplifiers for each channel. The combined
record/power output amplifiers can be switched be-
tween record amplifiers or playback power amplifiers.
The model 743 is similar to the model 74, but is fur-
nished with a playback pre-amplifier output stage, for
each channel, in addition to the combined record/
power output amplifier, and a center channel output.
The model 72 is the half-track version of the model 74.
The model 728 is the half-track version of the model
74 B.
All four models have exactly the same mechanical
system.
We hope that everyone concerned with our products
will find this service manual useful.
