IEC connector with fuse and switch

SO, on my amp(PASS Labs x250.8), the center contact is oriented to the LEFT and the fuse points in/out, NOT UP/DOWN....any thoughts?

“if the iec input is oriented so that the center contact is below the contacts on the left and right, then the hot is on the right side, and the arrow should point to the left”
@jw944ts, 

Going by the advise from TweekGeek, you would insert the QSA fuse with arrow ⬆️ pointing towards XLR/RCA inputs.

@lalitk,I appreciate you trying to help, but perhaps you didnt understnad my post....the use is oriented from the BACKSIDE of the amp toward the frontside, so neither of your suggestions are helpful

@jw944ts,

I have reviewed the back of the amp, it appears the fuse holder *IS* on the rear of the chassis, between the IEC inlet and the on/off power switch. The trick to removing the fuse holder is to use a small flat head screwdriver to pry open a little latch at the top of the holder and then use the screwdriver at the bottom of the fuse holder to begin to loosen the compartment. Once you pull out the compartment, the fuse orientation should be as I suggested in my last post.

If you need further assistance with fuse replacement, reach out to Mark at Reno Audio.

PS: Make sure the amp is off and disconnected completely from power grid for atleast 2 hours before you proceed with fuse replacement. 

@lalitk , your interest is appreciated.....I have had no trouble locating or opening the fuse compartment, and it is oriented as I have said...I contacted PASS LABS, who have told me that current flows from the  end of the fuse  located towards the inside of the amp towards the end of the fuse located at the backside of the amp....
