Transistor
monoblock power
amplifier
Musatoff PA-15M
I made
monoblocks under
the scheme of РА-14
and made case.
But I modified
schematic and
monoblocks get
new model number.
Specification
parameters of
monoblocks are
as on model
РА-20.
Monoblocks
participated in
tests conducted
by site
soundex.ru. With
minor
modifications,
this amplifier
circuit has been
used in the
design of the
amplifier
PA-20.
Transistor
integral
amplifier
Musatoff PA-14
This amplifier
has appeared as
development
designed to
order, HiEnd
amplifier for
car use
Canon Felix.
The amplifier
has four inputs,
the first of
them balanced
XLR, other RCA.
The amplifier
has an output
power per
channel about
120 watts into 4
ohms and 70
watts into 8
ohms. The
amplifier has a
high damping
factor and low
distortion of
all types. The
amplifier can be
operated by
remote control:
adjust the
volume of it and
break into the
StandBy.
As a further
development of
the project have
been made
monoblocks
Musatoff PA-15M.
Hybrid headphones amplifier Musatoff HA-2
When designing
the amplifier I
have used an
interesting
solution when
transistor
follower
included
inside the NFB
loop on the
second grid for
the triode
connection.
The amplifier
has a remote
power supply
unit.
The maximum
current that can
be given to the
load - 500 mA,
which makes it
possible to work
even in the
high-resistance
sensitive
acoustics. As a
further
development of
the ideas
contained in
this amplifier,
I am preparing a
new hybrid
monoblocks.
Multi-channel
preamplifier
Musatoff PR-2
The
eight-channel
preamp has ample
opportunity to
switch channels
are grouped in
four stereo unit.
The amplifier
oriented to
professional use
in a home studio.
The amplifier is
equipped with a
full-featured
remote control.
In the amplifier
is integrated
headphone
amplifier whose
circuit develops
solutions used
in the amplifier
Musatoff HA-1.
Solutions used
in this
amplifier were
further
developed when
designing
integrated
amplifier
PA-20.
At the moment,
there is a
courtesy copy of
the amplifier
cost $ 1200
When
constructing of
this amp I used
an unusual
field-effect
transistors
operating at
near-zero bias.
It
makes
possible to
construct
of
amplifier
without
capacitors at
the input and
output.
RIAA preamplifier Musatoff RC-5i
The amplifier is built on the balanced circuitry with only one voltage gain stage on j-FET and inductive active correction. Это позволило достичь очень высоких технических и слуховых характеристик.
A more detailed description is
here.
In the development of its circuit design addresses the issue of production of the new corrector.
Transistor integral amplifier Musatoff
PA-6
The amplifier
uses the balance
schematic, which
prevents the
signal passage
through a power
supply and
operates only in
Class A.
Although the
amplifier is
build on
transistors, it
does not uses
negative feed
back in signal
path. More
detailed
description is
here.
Prototype was discussed in
article
in magazine Radio.
