The Komet

 

Concorde

 

is a straightforward and easy to operate amplifier.  This manual is 

intended to help you “

 

get to know

 

“ your Komet

 

amplifier, and make use of the many different 

sounds which it is capable of.

 

 

 

 
FRONT CONTROL PANEL LAYOUT   

( left to right ): 

 

 

 

1.

 

Power Switch:

 engages the wall AC / power to the amplifier. 

 

2.

 

Standby  Switch:

  allow  the  amplifier  to  warm  up  for 

60

  seconds  before  engaging  the 

standby switch to the play position.  This action will allow for all of the tubes to heat up 
to the proper voltage required for operation and will help prolong their lifespan. 

 

3.

 

Pilot Light: 

illuminates when power switch is placed in the “ 

ON

 

” position.  The pilot 

light is a type #

 47

 

( 6.3

 

Volt )

 light bulb. 

( See troubleshooting section for bulb replacement 

information ). 

 

4.

 

Hi-Cut:

  this  control  allows  shaping  of  the  treble  response  in  the  power  amp.    For 

players who prefer a darker tone, the only option with most amplifiers, is to roll down 
the treble control.  The treble control is passive 

( reduces a portion of the signal )

, so the 

result is a loss of gain, and “

muddy

” distortion.  The Hi-Cut feature allows the Komet

 

owner to set the preamp EQ for the right balance. Then you can darken or brighten the 
overall tone using the Hi-Cut control without changing the basic EQ setting. 

 

5.

 

Presence  Control:

  affects  the  highest  frequencies  in  the  output  stage.  It  is  normal  to 

hear  a  “

scratchy

”  sound  when  turning  it  the  Presence  control.  This  is  due  to  this 

amplifier’s particular circuit design. 

 

6.

 

Bass Control:

 controls the low end range bass frequencies. 

 

7.

 

Midrange Control:

 controls midrange frequencies. 

 

8.

 

Treble Control:

 controls high end range treble frequencies. 

 

9.

 

Volume Control:

 controls overall volume and gain of the amplifier. 

 

10.

 

Input

 

Jack:

 accepts standard ¼ inch plug.  Input impedance is 1 Megohm.
