GENERAL ' INTRODUCTION

The TEAC AS-lOO is a newly designed stereo integrated amplifier of
the highest quality utilizing the latest circuit theory in its man-
ufacture. It's special features include a differential type power
amplifier unit which is direct coupled throughout all stages, and
an electronic protective circuit for the purpose of preventing
speaker damage from any malfunction.

This Service Manual is intended for reference and assistance to
service engineers who maintain and repair the AS-lOO.

The Model AS-lOO amplifier is thoroughly inspected and adjusted,
mechanically and electrically, prior to shipment from the factory
and is thus guaranteed to give perfect performance on opening the
shipping carton. Although this amplifier utilizes unique circuits,
quick repair is made possible by refering to this manual. The am-
plifier is designed for easy servicing.

This manual avoids extensive explanations and instead presents all
printed circuit board patterns, circuit diagrams and ample photos
for quick comprehension of parts layout. In the PC patterns, ex-
ternal circuits and their connecting points at each board are in-
cluded for easy circuit tracing. Furthermore, codes and numbers
are clearly indicated in the parts list and photos of parts layout
for convenience in ordering parts.
