GETTING THE MOST FROM YOUR ZEN TORII MK5 

Your amplifier comes with a lifetime warranty.  Probably one of the only amplifiers 

in production that has one.  Decware is a small enough company to consider these 

hand built amplifiers to be like our pets.  We like to keep tabs on them and make 

sure they’re healthy and happy at all times.  We don't want to see one get stuffed 

in a closet and go unused.

 

If you're not getting the sound you're after or grow tired of your amp we already 

know the 26 reasons that could have created this effect and would be pleased to 

offer some free consulting.

 

There are also over 100 articles written on the web site to this effect and active 

support forums for you to participate in. 

SAFETY 

You can’t get the most from your amp if your not around to hear it!  Never remove 

the amplifier from it’s wood base.  There are no user serviceable parts inside.  

With 

all tube amplifiers it is wise to turn them off when you go to bed or are away from 

home.  Tube amps are high voltage devices and tubes are in themselves imperfect 

devices so failures are possible even when the amp is just on not playing any 

music

.  Keep children away, tubes are too hot to touch.  Specifically the 5U4, EL34/

KT66 and 6922 will burn you.  The remaining tubes that glow bright orange (OA3 

and OC2) do not create any heat and are safe to touch while on.  Keep water away 

from amplifier at all times, especially when on.  A single drop of water hitting a hot 

tube will make the tube break and short out in the process.  Keep flammable items 

a safe distance from your amplifier and make sure the removable power cord you 

use is in top condition.
