PRECAUTIONS

 

 

 
TUBES ARE HOT

!

 

Make sure  you allow the tubes in  your amplifier to cool down before 

handling  them.  They  are  also  made  of  glass  and  can  easily  break.  Wear  safety  gloves  and 
goggles when handling audio tubes. 

 
DO NOT OPEN UP THE AMPLIFIER

 

There are no user serviceable parts inside. There 

are lethal voltages present even when unplugged. 
 

NEVER

:

 

replace  the  Mains  or  H.T.  fuse  with  a  higher  rated  fuse.  This  will  most  certainly 

cause severe damage to your amplifier.   

 
NEVER

: use a shielded guitar or instrument cable as a speaker cable connection. 

 

NEVER

: operate any amp without a speaker load connected to the output jack

(s)

.  

 

ALWAYS

:

 

make certain that your AC power cable is unplugged when replacing any fu

se.

 

 
ALWAYS

:

 

operate your Komet

 amplifier with the correct tube types listed in this owner’s 

manual.   
 

ALWAYS

:

 

use a three pronged, grounded AC power cable and always plug into a properly 

grounded outlet. Failure to do so may result in injury or death. 

 

ALWAYS

 

UN-PLUG YOUR AMPLIFER WHEN YOU ARE DONE

!

 

This is to protect 

your amplifier from surges in electrical power, or transient voltage. The standard American 
home  AC  voltage  is  120  Volts.  Anything  over  this  amount  is  considered  transient  and  can 
damage electronic devices that are plugged into an AC outlet. Though power surges are brief 
and  measured  in  nanoseconds,  they  can  cause  considerable  or  permanent  damage  to 
electronic equipment. Electrical surges can damage electrical equipment by burning or fusing 
internal wires or by the gradual degradation of a device’s internal components.

 The best way 

to prevent damage is to unplug your amplifier when not in use

   

 
NOTE

:

 

Devices such as refrigerators and air conditioners require large amounts of energy to 

switch  motors  and  compressors  on  and  off.  Such  devices  can  create  surges  in  power  that 
disrupt  the  steady  flow  of  line  voltage.  Lightning,  faulty  wiring,  downed  power  lines  and 
faulty equipment at the power source 

(utility company)

 can all cause power surges as well. 

 

ALWAYS

:

 

try to

 

keep your amplifier and/or speaker cabinet in a climate controlled setting. 

Failure to do so can be problematic. The tolex on your amplifier head box cabinet can shift 
and shrink in the Summer, especially if you leave your amplifier for an extended amount of 
time  in  a  sun  heated  vehicle,  trunk,  trailer,  or  an  extremely  hot  and  humid,  non-air 
conditioned environment. This is due to the glue used to apply the tolex to the wooden head 
box cabinet. The glue can become slightly molten from excessive heat, which can make the 
tolex movable, expand and then shrink when cooled. Excessive heat can only cause this tolex 
situation and this 

is not

 covered under your Komet

 

warranty.
