•   When moving your amplifier from a cold environment 

to a warm environment, condensation can occur inside 
the amplifier. Always allow your amplifier to acclimate 
to room temperature before operation.

•   Do not operate your amplifier in extreme hot or cold, or 

in wet conditions.

•   Keep your amplifier free of dirt, dust and moisture. If the 

covering of your amplifier requires cleaning, use a light 
soapy solution on a damp cloth. Avoid getting liquid 
inside the amplifier or on the control panel surfaces

•   Avoid rough handling, dropping or extreme vibration to 

your amplifier.

•   Always take care when transporting your amplifier.

•   Do not block the vent openings of your amplifier. This 

can cause the amplifier to overheat.

•   

If you notice a change in the performance of your 
amplifier, take it to a qualified service professional to 
diagnose the operating condition of the amplifier and 
the tubes.

•   Tube life varies based on the frequency, duration and 

level of use. Tubes require replacement from time to 
time to maintain top performance of your amplifier. If 
you are not sure about the operating condition of your 
tubes, take the amplifier to a qualified professional for 
evaluation of the condition of the tubes

•   Do not try to service or modify your amplifier yourself. 

This will void the warranty and presents danger of 
electrocution. There are no user serviceable parts inside.

•   

Always unplug your amplifier from the wall power 
source when not in use.

•   

Always have your tubes replaced by a qualified 
professional.

•   Never operate your amplifier without a speaker cabinet 

connected via an appropriate speaker cable (not 
instrument cable!) to the speaker cabinet.

•   Never operate your amplifier at an Ohm load below  

4 Ohms.

•   Always place your amplifier in “Standby” mode before 

turning it on, off, changing the setting of the Half Power 
transformer switch or the Triode/Pentode switch.

•   When in doubt, have your amplifier evaluated by a 

qualified professional!

Tube amplifiers are more sensitive than solid state 
amplifiers. Extra care will extend the life of your GT50H 
and the life of your tubes and ensure top performance. 

Here are some recommendations that will help you get the 
most out of the GT50H.
