MM-MC Phono Amplifier
Verdier Preamplifier
The Verdier Turntable is manufactured in little
series for more than 20 years and his success is everyday bigger. It became
necessary to complete it with a high quality pre-preamplifier able to drive
the signals of a moving coil cartridge in the best conditions.
The new MM MC phono Amplifier is now entirely ready for work and its
performances are the best ever made.
It is composed of 4 chasses : 2 regulated power supply and 2 correction
Amplifiers.
It uses 36 tubes.
Each pre-preamplifier is composed of 12 Triodes (1/2 7 DJ 8 - PCC 88) in
configuration of distributed amplifier for a best signal noise ratio.
These Triodes are powered by 4 regulators which additionate their
stabilisation factor to the one of the separate power supplies.
The RIAA de-emphasis of the MM MC is passive ; it is completed with a
balance circuit and makes possible a balanced connection with the power
amplifier. Never before a manufacturer has made a so sophisticated product
for the amplification of a phonographic signal.
Our hope to achieve the best result without thinking about cost was the same
than 10 years ago when we created the Turntable.

Dual Regulated Power Supply
Control B Pre-Amp
That new preamplifier is built in a modulated
structure, that is to say that the different functions are reassembled on
removable PC boards and all is foregone to add - without any adjustment - at
each moment a new PC board, either to hold a new function, or to "upgrade"
an existent function.The housing is engineered to carry out a maximum
rigidity by the using of a 25/10 thickness steel sheet which protects in the
same time against the different electromagnetic rays. The front plate is
available in 2 versions; one is standard light grey lacquered and the other
in 10mm aluminium finely brushed and champagne coloured.
The external power supply conducts to a very attractive, signal/noise ratio
especially on the Phono position. A luxury power supply (see photo) is sold
in option : Dual regulated power supply.
INPUT SELECTOR AND WIRINGS : When it is fitted with all its removable
PC boards, the preamplifier CONTROL "B" has 5 stereophonic inputs and one
input/output in monitoring for Tape recorder which maximum sensitivity and
impedance are specified in the following chart : The volume adjustments are
made by separated potentiometers on each channel.
LINE AMPLIFIER : The line amplifier works for the amplification and
the impedance decrease necessary to connect a source to a power amplifier.
Each channel is made up of 3 triode tubes (1/2 12AT7, ECC81, 6201).
The first stage wired in cathode follower gives a large input impedance and
modulate the second stage wired in µ follower which gives the amplification
and the low output impedance. The absolute phase is observed. The gain is
foregone for 0, 6, 10, 14 and 20dB.
PHONO AMPLIFIER : The phono amplifier is engineered to realize the
de-emphasis according to the RIAA norm and the very important amplification
enough for the moving magnet cartridges - 2 transformers with µ metal
magnetic circuit allow the using of moving coil cartridges - Each channel is
made up of 3 triode tubes (1/2 12AX7 , ECC83 , 7025 ) with very low noise
and very low microphonia. The first stage wired classical manner with a
metal resistor in an anodic circuit drives a second stage wired in µ
follower, that last sends back in feedback by a RC filter a part of the
signal in the first stage cathode and gives the RIAA correction respected
until 20 Hz. Designed very carefully around original diagrams and
scrupulously produced, we are certain that our new preamplifier CONTROL "B"
will be classified soon among the best available products, without regarding
on the sale price which stays reasonable.

Dual Regulated Power Supply For Control B
Our new amplifier Control B is a surprising
quality fitting, its low price and its little size could let think that it
is an ordinary apparatus, we thought that it was necessary to give it more
prestigious features by reinforcing its power supply device.
Now the "control B" is available with the "Dual regulated power supply".
That power supply totally electronically regulated, includes 3 tubes, 1
rectifier 5Y3 provides the direct current to the regulation device
constituted by a low internal impedance tetrode 6Y6 working with a sharp cut
off pentode EF 184 which issues the amplification of the error signal.
The whole fitting allows maintaining the power supply of the preamplifier
perfectly constant even if the main voltage varied between 170 V and 260 V.
The power supply is hold in a 2 mm steel sheet housing ventilation holes
widely provided with.
The front plate calling to mind the look of "control B" is constituted by a
10 mm champagne coloured aluminium plate finely burnished and brushed.
-Power Supply 230V/50Hz – 117V/60Hz
-Power Consumption 30 Watts
-High Voltage Output 320V – 30 mA
-Low Voltage Output 18V – 0A6
MC Pre Pre
The MC PRE PRE is an active step up device created around an extraordinary operational amplifier.
Running in classe A, it combines extremely low
noise with transparency and neutrality - qualities you come to expect in
more expensive equipement. An outboard power supply is used to avoid
electronical field interference with the signal.
-Power requirement 220 Volts or +/- 12
Volt DC
-Power consumption 4 Watts
-Input Sensitivity 0,2 mV (R.I.A.A.)
