Introduction - DYNACO Stereo 80 Owner's Manual

Introduction

Congratulations on your purchase of the Dynaco Stereo 80 Amplifier. This product was
designed to provide the highest combination of quality and value available, which is the
Dynaco tradition.
The Dynaco Stereo 80 amplifier uses special power supply buffering circuitry - found
in no other brand of amplifiers in this class. We have included a separate buffer circuit
for each of the input and driver tubes in the Stereo 80, allowing each amplification stage
to function more independently, (as if each one had its own separate power supply).
This method contributes significantly to the sonic clarity of the Stereo 80.
The Stereo 80 can be operated in either Triode or Ultralinear mode. Switching between
the two is easily done via a front panel switch.
State-of-the-art biasing circuitry allows you to easily attain precision bias settings for
each of the output tubes through front panel adjustments and indicators.
Another special feature of the Stereo 80 is its adjustable Input Sensitivity. This allows
the Stereo 80 to be connected directly to components having vastly different output
signal levels. The user can, for example, connect a CD player directly to the Stereo 80
without using a preamplifier.
You will find the Stereo 80 sounds better than the large majority of other amplifiers -
both solid state and vacuum tube designs - regardless of price. Your Stereo 80 was
designed and built entirely in the USA. We are proud to offer this outstanding amplifier
to discerning audiophiles the world over.
