Break-in period: 

It is recommended to allow the amplifier to operate 150+ hours so that peak 

performance can be realized. An effective way to break-in the amp is to run the amp 
normally with music playing.  

Please do NOT leave the amplifier ON while away and unattended. 

 

Warning: 
 

The amplifier MUST have a “load” via the headphones or speakers (WA5) when powered 
ON. Running the amplifier without a “load” could damage to power transformers.
