Conrad Johnson Premier 140 fuse is blown

Hi Audiogoner.
I need your advise on what I should do now.
This morning, my amplifier’s fuse has blown on the left side while listening to music. 
Should I change the fuse and power it back on or should the amp be checked up by a technician?
 Thanks for the advise if any. I have no knowledge on electronics.

Make sure that the speaker connection did not come loose. That will also blow a fuse!

What kind of fuse ? Please remember a stock steel bus fuse can vary up to 
15% in value , precision fuses like Hifi tuning Supreme  Synergistic are within 
1%  and can blow quicker, it happened to me several  times ,I go one small step up in size with a premium fuse still plenty of protection 
like from a 3 amp fast  to a 3,125  fast blow.

The first tube I would look at would be the rectifier tube if your amp has one.

Hello all,
After the replacement of 8 KT-88 Reissued Gold Lions which I purchased from Upscale Audio and the KTK-1 fuse, my Conrad Johnson Premier 140 is working as normal. 
Thank you all who have sent suggestions to help me.
