It looks like the fuse in on an AC line which means no matter how you install it it will be in the right direction 50% of the time.
Sony XA5400ES fuse directionality...
Hello! I just purchased a pair of Hi-Fi Tuning (directional) fuses to upgrade the stock ones, and was wondering if any 5400 owners have discovered which way the current flows through them in this player. Do the arrows point to the right or left when viewing the fuse holders from the front of the player? Thanks for your help!
