- This knob controls the amount of gain
in the tube stage, and provides an extra gain all
the way up to 34 dB. This control also com-
presses the sound when turning up the level of
the knob up to maximum, producing pure tube
limitation.
- This filter section contains
two high performance filters for fine tuning your
drive channel sound:
has a frequency range of 50-2k Hz
and facilitates total control all from the bass
timbres up to the mids, controlling with
precision the difinition of the mids.

DRIVE CHANNELOPTIONS:
BOOST
SERIAL
- This knob controls the level of the
channel. The drive channel must be
activated for this control to work.
- This knob controls the level of
the channel to be mixed in with the
channel sound. The drive channel must be
activated for this control to work.
– The boost switch makes possible a
choice of two different overdrive types. When
this switch is in its' inner position a flat, or linear,
gain is achieved with the knob. However,
when this switch is in the outer position, the
frequencies below 350 Hz is bypassed,
producing a warmer distortion without
saturation, allowing the player adding more low
bass than with conventional bass amps. The bass
is compensated over the tube stage, giving the
same bass response up to mid distorted sounds.
- The serial switch selects the source
for the drive channel. In outer position the
source is taken directly after the gain and
preshape filters. In inner position, the source is
taken after the clean channel, including all of the
clean channel features; filters, compresssor and
tube buffer.

SPEAKER OUTPUTS
AC INPUT
SYSTEM FAN
– Connect your
speakers here. Care should be taken when
connecting speakers so that the minium total
impedance is not lower than 2 ohms.
– Connect only to the indicatedAC
voltage. If the mains fuse blow, replace only
with the same type.
– The system fan is a tempera-
ture controlled fan and will increase the speed
according to the temperature and power output.
Note: Lower impedance than 2 ohms may cause
permanent damage to the amp.
EBS will not take responsibility for
eventual hearing damages caused by the
powerful EBS Fafner.
IMPORTANT: Make sure not to cover the
ventilation opening!
SOMETHING ABOUT TUBES…
Although the ECC83 (12AX7) is a long life tube,
it is recommended replacing the tube once a year
to guarantee perfect operation.
In order to replace the tube, please follow the
instruction below:
1) Power off and unplug the amplifier from the
mains.
2) Let the amplifier fully discharge for at least
five (5) minutes.
3) Remove the top cover by removing the four
bolts at the amps left at right side, and the two
bolts on the top cover next to the rear panel.
4) Locate the tube at the poweramp board and
carefully remove the tube.
5) Place the new tube in place. Be sure that no
tube pins are damaged.
6) Place the top cover in place.
Done!
