Many thanks for sharing your thoughts and advice.
I will check the tubes as suggested by Hifigeek1 and will also check the tubes are operating with a bais of .65mv as suggested by Smoffatt.
Hifigeek1 could be right regarding a faulty tube (despite the tubes are new with less than 100 hours usage). Next, I will check on the socket as suggested.
Last week, ARC technician did suggest I should swap the tubes from the working Amp to the Amp that I am having problem with the blown fuse. After swapping and if the fuse still blows, then I should try swapping the caps from the good amp to the bad amp. I hope this will narrow down the uncertainty of tubes or caps being faulty.
I will report back with my progress. Wish me luck and keep your suggestion coming!
