Problem with BAT VK 3000SE


Dear All,
               I am from India and I am having a Balanced Audio VK3000SE Integrated amplifier.  The amp. goes automatically to MUTE mode after playing for about 30 minutes.  While the sound is completely muted off, the display shows  "FAULT RIGHT".  I am helpless and it is very difficult to get it repaired I will ve very thankful to you if you are helpful to me in fixing this problem.  Thanks a lot.

@gnanasekhar are you reading these responses?  The volume is irrelevant.  Swap the tubes!  Jeez!!!

I am very sorry for not properly respond to your suggestions.  I tried to remove the tube and it is concealed and very difficult to remove and I am trying to find a technician to remove it.
