DOA 016

 It enable to replace DOA016 with the
class A line driver for JC-2, ML-1,
and ML-6.

 

The circuits of DOA016 are configured
the 
two stages of the differential
amplifier and 
the output stage of
push-pull buffer.

The differential amplifier of the first stage
is made up of the dual-FET driven
constant current control.

The dual FET of this stage is the
most important 
device for giving
high-quality sound.

 The dual FET was carefully selected after   listening check over and over again.

 The differential amplifier of the second  stage is made up the PNP transistors of  matched pairs.

 

The current of the class-A operating
area is controlled by this stage.

 Usually the out put stage operates by complemented NPN and PNP transistors.

 

DOA016 are made up of the finest
available discreet parts and devices
which are monolithic dual FET, matched
high quality trasistor selected mica &
polycarbonate film condensers etc..
