throughout.
The
use of a Dual
FET
input and a cascode
bootstrap
circuit
in the first stage and a cas-
cade-connection,
current mirror and push-pull
output
in the
pre-drive stage ensures
a high
degree
of
stability,
low
distortion
and
im-
proved high-frequency characteristics.
In the driver and the power amplifier a three-
stage emitter follower
is pure complementary
OCL
SEPP circuitry using high-ft transistors.
This accounts for wide bandwidth, high output
and low distortion.
voltage amplifying stage, and the use of a pure
copper plate earth line for ultra-low impedance
guarantee greatly reduced intermodulation dis-
tortion,
improved
separation
and
absolutely
stable operation.
Other Features
Except for the chemical capacitors in the power
supply section, mylar and styrol capacitors are
employed throughout.
Layout
of parts, wiring,
earth line as well as
many
other aspects have been given due con-
sideration.
The basic design ensures high reliability, while
the ultimate aim has been the improvement of
the overall audio characteristics.
