VACUUM TUBES I NSTALLATION
Place the amplifier on a stable surface. Carefully remove the vacuum tubes from their packaging and install them in the appropriate sockets, as show below, and adhering to the numbering scheme as identified on the packaging.

WARNING: The pins in the base of each of the vacuum tubes are “coded”, and this has the result that the insertion of the vacuum tube into the socket is possible only in one correct and appropriate orientation. If, whilst inserting the vacuum tube you will sense resistance, and you can not push the tube into the socket, please check the orientation of its pins, rotate the tube to the correct position and try again.

WHERE TO PLACE YOUR AMPLI FI ER
Due to the presence of high temperatures during normal operation of the vacuum tubes, the location that you pick to place your amplifier should ensure ample ventilation, a free flow of air. Please maintain at least 10 cm clearance between the housing of the amplifier, together with the vacuum tubes, and other devices or elements of the interior.The sound quality may be degraded as a result of vibrations. Therefore we recommended to place the amplifier on a flat and stable surface.

WARNING: Never place the amplifier near the source of heat.

WARNING: To avoid electrostatic shock to the components of the amplifier, please touch a grounded conductive surface before making any connections .Any and all connections must be made whilst the device is disconnected from the mains power supply. Before making any such connections, make sure that the amplifier is switched off.

Follow the instructions below to connect your sound system correctly.

STEP 1 S PEAKERS CONNECTIONS
Check the impedance of the speaker set. Connect the speaker cable to the appropriate terminals on the rear panel of the amplifier. Depending on the impedance of the speakers, connect it to the terminal marked either 4 Ω or 8 Ω. If your speaker impedance is 6 Ω – connect the speaker wire to the terminal 8 Ω.

WARNING: NEVER TURN ON THE AMPLIFIER WITHOUT CONNECTED SPEAKERS

STEP 2 AUDI O S IGNAL SOURCES CONNECTIONS
Connect the signal source to the amplifier inputs IN1, IN2 or IN3. Select the source of input signal by rotating the input selector located on the front panel of the amplifier. In order to achieve the highest sound quality, use only high-quality RCA cables. Pay attention to the proper connection and distinction of the right (R) and the left (L) channels. For the best sound quality, we suggest using the Fezz FAC 01 interconnect cable dedicated for Fezz Audio vacuum tube amplifiers.

WARNING: To connect a turntable, you will need to use an external phono MC/MM preamplifier or turnatble with a built-in preamplifier.

STEP 3 POWER CORD CONNECTION
Make sure that the amplifier is switched off. Connect the power cord to the IEC socket on the rear panel of the amplifier. The amplifier is designed to operate at a rated voltage of 230V / 50-60Hz. Connecting the device to a mains network with incorrect parameters can lead to damage that is not covered by manufacturers warranty.

FIRST POWER-UP AND GETTING

Make sure that all of your wiring is connected in accordance with the information as provided above.
Select the source of signal using the rotary selector switch located on the front panel. Set the volume control to minimum. Turn on the mains power of the amplifier – the vacuum tubes shall begin to glow. Make sure that the sound source is turned on, playing, and then gradually increase the volume level by turning the potentiometer.

The operation of the amplifier narrows down to adjusting the volume via VOLUME potentiometer and selecting an audio signal source via rotation of the SOURCE switch.

BUR I NG-I N PROCESS
Any tube amplifier requires an initial pre-heating (or „burn-in”) period, in order so that it achieves its full sonic potential. This is due to the presence of residua polarization of dielectric elements and due to a necessary stabilization of working parameters of the vacuum tubes. The stabilization of the electrical parameters of the system occurs in a natural process whilst playing music through your audio system.
A preliminary degree of pre-heating of the amplifier is reached after about 10 hours of quiet music playback. Full sonic capabilities shall stabilize and unfold within a time-span ranging from 40 to 60 hours of music reproduction at a moderate volume levels.

VACUUM TUBES REPLACEMENT
Your amplifier is equipped with automatic bias module. It’s necessary to use vacuum tubes that have previously been pre-selected and paired up in quads or pairs. REPLACEMENT OF 12AX7 DRIVER TUBES for 6n2p or vice versa

1. Disconnect the amplifier from the mains socket, the power supply network.
2. Remove the currently installed tubes from their respective sockets: 2 and 4. Plug in the new replacement vacuum tubes in these sockets.
3. Set the 12AX7 / 6N2P tube type selector switch to the position which is correct for the chosen type of replacement tubes

POWER TUBES FUSES REPLACEMENT

Every power tube has its own safety fuse (symbol – m100mA). When power tube will fail. Safety fuse will blow and prevents any further damage of the amplifier. Please replace foulty power tube with new one. Replace the power tube fuse with new m100mA if needed.

OPTIONAL EQUIPMENT

VACUUM TUBES PROTECTI VE CAGE HT (PRE-I N) I NPUT
The additional HT (Pre-in) signal input makes it possible to use this amplifier as a stereo power amplifier. In order to make this possible, it is necessary that you have a separate preamplifier with its own volume control, or a receiver with ‘Pre-out’ output.

WARNING: Never directly connect sources such as a CD player, DVD player, BluRay players, DAC or similar devices to the HT (pre-in) input. The HT input is specifically and exclusively designed for use with preamplifiers with adjustable output volume and with recivers which are equipped with a „pre-out”
