Conrad Johnson Premier 140 fuse is blown

Hello again.
my amp is working as normal. The sound come out beautifully with no distortion in both channels. 
BUT,
when I look at the amp from the front, there is one tube out of eight total glow brighter than others. I checked the old tube in that position, and figured out that old tube was bad, I can see the smokes deposited on the glass. 
Is it just a coincidence or do I need to bring the amp to see the tech?
Thanks
Calvin

Never mind.
I switched tubes and the bright glow tube followed to the new position. 
Should I contact Upscale Audio to exchange the tube?
 Thanks 

From indications; that would be a good/safe idea. Did you carefully follow the manual’s re-biasing procedure, for each tube, repeating it after 30 minutes? That should have also been performed, after the glowing tube was moved.

Yes I did bias the tubes indivitually.
Thanks.

Upscale should agree, you’ve done your due diligence.  Kevin does(typically) take very good care of his customers.
