Important: Study the owners manual before assembly and operation of the amplifier
Anyone, unable to comprehend the instructions stated in the owners manual should not operate the
device.
Children and minors are not to use the device and should be kept at a safe distance from the
device while it is running.
The user is responsible for operating the device in an appropriate fashion and it takes full
responsibility towards third parties. Before the amplifier can be used the first time, suitability of taken
precautions regarding electrical safety must be approved through professional assessment.
Check that the mains voltage printed on the rear panel of the amplifier corresponds with the line
voltage in the territory where you intend to use the amplifier.
Always check powercords and plugs for damage before use.
Disconnect the powercord before work is being done on the amplifier.
In the unlikely case of a failure of the device repairs may be performed by
AUDIOVALVE authorized technicians only. Use
ORIGINAL spare parts only!
Please take note of the fact that we waive product liability for damages caused bij our devices,
parts and components as a result of:
a) Unprofessional and / or faulty and / or correct repairs that have been performed in other
than the by AUDIOVALVE approved repair facilities,
b) Usage of other than ORIGINAL and approved spare parts.
The SUNILDA Pre-Amplifier is subject to and complies with German security class 1
for devices with metal housing. The device is grounded, and may not
–
by manipulation or otherwise be ungrounded for any reason! To prevent hum as a result of interconnecting your devices with the
SUNILDA Pre-Amplifier, the internal electrical circuitry has been designed to have no grounded
mass!!

Description
Sunilda is a three stage phono-preamplifier, based on 6922 (ECC88) and 12AX7 (ECC83) frame
grid tubes, suitable for MM- and MC-cartridges. Independently for the two phono inputs, impedance
and capacitive load can be set separately and 'on-the -fly' while listening. Thus the user can easily
configure the unit to match the features of the cartridge by selecting the optimal input resistance and
capacitance for each input separately! Sunilda comes in an laser cuted 3 mm thick steel, chassis in
black or silver finish and has a case similar to the Eklipse line amplifier.

Switches are found for: MM/MC mode for each input; input 1 or 2; selectors are used to select
different R and C loads. Two selector knobs for each input capacitive and resistor load

In MM mode the gain will be 20 dB lower than MC and at a fixed input- impedance of
47K.
In MC mode the preamp will have higher gain and switchable input resistors and condensers. The
RIAA de-emphasis is passive and split between the first and second stage. Dividing the RIAA
network over two amplification stages lowers the insertion losses of the passive network
dramatically. Furthermore, the design holds a total absence of feedback, thus increasing the overall
dynamics.

The power supplies are solid state regulated. This is the best way to obtain a low
noise and supply line with a very low impedance that will increase the performance in the
lower frequency range. The power transformer is housed in a separate aluminum case. The

turntable earth grounding terminals ( black posts ), 2 RCA cinch output jackets and 2*2 input
RCA jackets.
