BACK CONTROL PANEL LAYOUT
(left to right):
1.
AC Input
: this IEC receptacle accepts a standard DIN AC 16 gauge, three conductor
power cable. All Komet
amplifiers can be internally modified to operate on either
120V
or
240V
only. Please inquire with Komet
Amplification for AC conversion information.
2.
Mains Fuse
:
3
Amp
"
slow blow
"
fuse
(
a.k.a.
MDL 3A - size: ¼ inch by 1 and 1/4 inch)
is
used on
120V
model, a
2
Amp "
slow-blow
" fuse on the
240V
model.
CAUTION
:
ALWAYS MAKE SURE YOUR AMPLIFIER AC CABLE IS UN-PLUGGED BEFORE
REPLACING A FUSE
.
3.
H
.
T
.
(High Tension)
"
fast acting
"
fuse:
1/2
Amp or 500mA
(a.k.a. AGC 500 mA - size: ¼
inch by 1 and ¼ inch).
Should the H.T. fuse repeatedly fail in your Komet
amplifier,
replace the fuse and replace the EL84/6BQ5 power tubes with a new quartet with the
correct IP
(plate current draw)
rating
(see bias section)
. Your amp may need servicing by an
authorized technician if the problem persists.
CAUTION
:
NEVER REPLACE ANY
FUSE WITH A HIGHER RATED FUSE
.
This will
most certainly
cause severe damage
to your amplifier.
4.
Output Impedance Selector
:
set this selector according to the appropriate speaker
impedance you are using.
4
,
8
, and
16
Ohm settings are available.
5.
Output
Jacks
: two, standard ¼ inch speaker jacks, wired parallel, which will
accommodate any quality standard speaker cable.
Note
:
never use a shielded guitar cable
as a speaker cable.
You can severely damage an amplifier.
6.
Tube Chart
: displays the placement of the power and pre amp tubes
(V1 to V7)
.
7.
Fast / Gradual
:
switch enables the musician to alter the response characteristics of the
amplifier to suit their playing style. A simple flip of the switch lets you choose between
two different responses to your picking dynamics and guitar’s volume control settings.
This is not an extra gain stage or gain boost circuit. Instead it functions by magnifying
subtle changes in pick or finger attack along with subtle changes in guitar volume. The
Gradual
setting of the circuit allows a clean player to run the full range of dynamics
without breaking into unwanted distortion. You can play on the edge of distortion easily
going from clean to blues overdrive using pick attack as the controlling factor. An over
the top player can go from clean to scorch using the
Fast
setting. The slightest change in
pick attack or guitar volume setting will translate to huge changes in dynamics and
power. To sum it up, this function lets you choose the response and feel you want and
makes your amplifier capable of playing every style of music desired.
Note
: you will hear a "
thump
" coming from the speakers when the Fast / Gradual switch is
engaged in the "
Play
" position. This is normal, part of the circuit design, and is not indicative of a
problem with your amplifier. We recommend that you engage the "
Stand By
" switch before
changing the Fast
/
Gradual switch setting to avoid this sound.
