HOW TO USE THE AMPLIFIER IN ORDER TO PROLONG TUBES’ LIFE-SPAN

1).  The amplifier should always be switched on in the following way: first turn 

Power

 on and wait 

for 1 minute. Then, you can turn the 

Standby.

 Switching the amplifier off is the other way 

around – first turn 

Standby

 off, then wait 1 minute, then you can turn power off.

2).  Always use a matched quartet of power tubes, from Laboga or renowned producers.

3).  Before transporting the amplifier, wait for the amplifier, especially for the tubes, to cool down.

4).  When you don’t use the amplifier, it is advisable to regulate 

Standby

 to position “0”

5).  An excessive amount of dust on the tubes may decrease heat distribution of the tubes, which 

could shorten tubes’ life-span.  Use an original Laboga cover or hard case to prevent damage 

and dust.
