New Product Information
Stereo Tube Power Amplifier
/ Integrated Amplifier
Model
A-100
ESOTERIC is proud to introduce a stereo tube power
amplifier incorporating exceptionally high quality and “cutting
edge,” tube technology.
The A-100 provides 45W / ch output power from KT-88’s in
UL-Push / Pull operation driven with a direct coupled
cathode follower. The cathode follower and voltage
amplification stage is directly coupled to form a triple stage
by combining a unique and active bias circuit.
The A-100 is truly an innovation leading conventional tube
technologies to the “Next level!”
-
Directly-coupled triple stages
The DC voltage control circuit ensures stable operation
of the directly-coupled triple stages (voltage
amplification stage, cathode follower stage, and output
stage), achieving a truly involving acoustic expression
from the A-100.
-
Unique active bias circuit
The A-100 features a unique and advanced active bias
circuit. This circuit compensates the bias voltage
supplied to the output stage, detecting the cathode
current and the driving level. High linearity and superior
performance of the output stage is achieved by optimal
bias voltage control from this new design.
-
Custom output transformer
The A-100 features a newly
designed custom output
transformer achieving highly
delicate and precise musicality.
The amplifier uses specially
treated dual layer foil (copper
and silver), as the 2
nd
order
coil. This design provides very
tight coupling properties
between the 1
st
order coil.
